@amaity: This sort of question is best answrered by the folks on the Xilinx Forums (go to the Xilinx Website and search for Forums) -- they have experts there who know all about thsi sort of thing.
i cannot able to execute some benchmarks like xge_mac,mmcfpgaconfig in xilinx ise 14.3.
please help me to solve this problem. tell the procedure to solve this benchmarks in xilinx.
@ALL: - OK, I will close it now. Tchau! :0)
@ALL: Thank you so much for all the input on the MSP430. I got interested in the series because of the ULP feature to build "motes". Some of the parts already run the Berkley TinyOS.
The 430 is a bit weird -- requires really tight voltage regulation to run reliably at max speed
I've got to head off too. Bye all.
The pricing on the MSP430 Launchpads and booster packs is sure in the right place.
Intseeker - I just found the blog where I mentioned it. I saw it in September 2009
Intseeker - My booth at the Embedded Systems conference was right next to Ti's a few years ago. Maybe four. Jason Kridner, who is also one of the designers of the Beagleboard, was showing an MSP430-based digital clock he made that was powered by three grapes.
OK -- I have to go also -- I need to rest up a bit -- hope to see you all next week -- more later -- Max
The thing is that with smaller geometries, radiation events are going to affect chips in ground-level applications
@ALL: yes, a lot of fun and info to digest. I will come back to the archive later to get the rest of the talk. See you next time.
I need to go to. CU all later.
@intseeker, I think my first MSP430 project was in 2006 or 2007.
All, been fun. I gotta go. Have a good week(end)!
rfindley: I was under the impression they staterded in 2010 with V1.0. Did I miss something?
Most of the uProcessor vendors do not even consider soft events at altitude when giving out MTBF for their parts even thought they operate at the same core voltages as many FPGA's -- they have not even considered Radiation effects at altitude for their designs
@Jake: Not to let too much outta the bag, but the aptina thing really caught my eye, as I have a couple of those sensors sitting on my desk, awaiting their time for a project...
Intseeker - I have a few and have fiddled with them a bit, but I wouldn't call myself knowledgable on the platform
@intseeker, I've used the MSP430, but it's been probably 4yrs ago.
@tomii - These boards are more "fun" and less "business" like the XEM3005.
@ALL: - before I take off, anyone present works with the TI MSP430? I have been reading about the series and lately playing with the LauchPad and doing some tutorial ...
@Jake: Woohoo!
And thanks!
@William: BIT, PBIT and Redundancy for Radiation Considerations are a considerably formidable topic
Yes, but a very interesting one -- also you have to consider where the radiation event occurs, -- registers, RAM buts, combinatorial logic, clock buffers (nasty), configuration cells -- external configuration memory ... Oh My!
Max - I'll ask him tonight. Hopefully he can remember where he read it.
@MAX: The error detection/correction went away for a few years when they went to plastic packages. Then when they got to "big" memories, they had start adding in all the ECC stuff again.
There's a couple different ways to look at radiation vs/geometry size. The decreasing geometries seem to have a good effect towards total ionizing dose (TID - how "rad hard" the device is) - primarily because they are going to thinner and thinner substrates in the process (most are SOI now, right?)
SOI is also good news for latch up events.
My understanding towards likelihood, though, was that the likelihood was pretty similar for the smaller geometries, as the ratio of used vs unused space was pretty similar. And, being SOI process, less likely to affect multiple transistors...
Now, though, there's this whole push related to low dose rate effects and testing. *rols eyes*
@Warren Miller: DNA storage ... - I will do some digging on this.
@Duane: My son mentioned the DNA memory and four strand DNA to me. I haven't had an opportunity to go check it out though.
When you do get the time, can you email me any links to articles that you find please
@Jake: Been lurking... We're shipping to you today, Tom.
Cool Beans -- something I can take off my "To Do" list :-)
BIT, PBIT and Redundancy for Radiation Considerations are a considerably formidable topic
My son mentioned the DNA memory and four strand DNA to me. I haven't had an opportunity to go check it out though.
@duane You are using an HDL to describe the behavior of a hardware block. The sequential semantics are simply there to make that easier - the point is to decouple that kind of semantics from the idea of "software"
Re FPGAs and radiation -- there's so much interesting stuff going on -- I was planning on writing some blogs about it -- but now I think I'll wait until after my talkk at Design West (I don;t want to give the game away)
Been lurking... We're shipping to you today, Tom. Tied up waiting on the XEM6002 supplies.
@intseeker- Heard it on the radio- Public Broadcasting. It was on the BBC news hour a day or two ago. You might be able to find it there..
Bye marlowg (I bet your next meeting isn;t as interesting as this one :-)
It doesn't seem like that long ago when parity RAM was still an option.
@Warren Miller: DNA for permanent storag ...
Do you have a reference for that?
As part of my radiation talk at Design West I'm creating a Theatrical Prop -- see also my blog Danger, Will Robinson!
The tricky bit is going to be to get this to California without being arrested :-)
@all: Bye everyone. I have another meeting. Thanks!
All the level A flight hardare I've worked with that used DRAM used ECC, as did the NAND flash
@tomii: 9th bit was parity to detect bit flips due to radiation from the ceramic packaging.
As the feature sizes of the structures on the silicon get smaller, they are more suceptible to radiation events -- thsi is particularly true in the case of memory chips, which tend to use the latest and greatest technologies.
Not just 1-bit parity now, but mulri-bit ECC (error correcting codes)
Tomii - I actually have been around long enough to have had a PC with parity bits.
@Duane: Yeah, know the feeling. Wish my blogs were coming out as fast as I'm writing them, 'cuz I could sure use some thoughts right now. As it is, I'm going to stumble along and write something horribly wrong.
As an aside, 2 wrongs don't make a right, but 3 lefts do...
@tomii: I was curious about the operation...
Nothing to worry about -- found a small "lump" -- had it cut out -- looks benign -- will hear the formal results from the biopsy in the not-so-distant future
@Max: I was in Space Systems work for a while. I have an idea about radiation. Interesting tidbit most newer folk don't know:
Q: Why did the old PC's have 9-bit RAM?
A: 9th bit was parity to detect bit flips due to radiation from the ceramic packaging.
@rfindley: There was also a news article a few days ago about the discovery (or invention, I'm not clear on which) of QNA... quad-strand.
That sounds interesting -- I'd like to know more
Tomii - I get an idea in my head, it doesn't work, and then I keep bludgeoning myself with it.
One of the chapters in "The Violinist's Thumb" talks about how radiation affects DNA (and how DNA tries to recover) -- I'm going to include this in my talk on radiation at the forthcoming Design West conference and exhibition
@Max: I was curious about the operation...
@tomii: So, you're Mrs Crusty, now, or what?
Lake I say, I'm a bit slow today -- that one went right over my head :-)
@Duane: Well, I get an idea in my head that I wnt to try something, and then it doesn't work, so then I use google, and then that doesn't work. Wet, Lather, Rinse, Repeat...
@Warren/Max, There was also a news article a few days ago about the discovery (or invention, I'm not clear on which) of QNA... quad-strand.
@rfindley: Anothrer incredible book is Wetware: A Computer in Every Living Cell by Dennis Bray (Click Here to read my review).
I woudl class this as one of the most interesting and thought-provoking books I ever read.
Tomii - "Stumbling around a lot"; I'm familiar with that concept.
@Duane: I wouldn't go so far as to say I'm learning anything, but I'm certainly stumbling around a lot. I've been doing a lot of my work with *gasp* schematics...
@Max: So, you're Mrs Crusty, now, or what?
@Max- Did you hear the recent news article about using DNA as long term storage? Some researchers created DNA that stored an MP3 file, PDF, etc. They claim it will stay safely stored for 1K years...
@tomi: can you ping me tomorrow about Opal Kelly and I'll ping them -- I'm a bit sluggish (battered and bewildered) at the moment -- recoving from an operation yesterday -- resting up today -- back in the office tomorrow
Tomii - I've been learning Verilog and am now going to attempt to learn some VHDL. It kind of makes my head spin to jump back and forth between software and FPGAs.
@Rfindley: DNA is an absolutely fascinating subject, especially to the communications engineer!
Funnily enough, the chapter I just read in "The Violinist's Thumb" was on codes and redundance and how DNA strives to detect and fix errors and so forth.
@Max: I've seen nothing. I think they said something about 3 diff't pieces, but that's the last I've heard. Of course, free, no-strings-attached toys? Yeah, I won't complain if they don't show up right away!
I wouldn't mind having it, though, that's for sure - I'm doing dual development rightnow - learning verilog/FPGA's during lunch hour, or whenever, and trying to do software integration at home. It's kinda hard trucking stuff back and forth.
@intseeker: Is that another recipe for isomnia?
Well, I couldn't put it down, so I think it's safe to say that it kept me awake :-)
By Jack -- hope to see you (and your next blog) soon :-)
@MAX - Did you ever read "The Disappearing Spoon" by Sam Kean (click here to see my review). Is that another recipe for isomnia? :0)
@tomii: I'm with Duane -- I've really enjoyed all of yoiur blogs -- did the Opal Kelly folk ssend you their latest board yet? If not I will "ping" them for you...
@Duane: Well, you're the only one it seems. Although the last seemeed to get an interesting conversation going on the utility of development bords like those I'm using, and their features vs price point....
@Max, I may have to check out those books. DNA is an absolutely fascinating subject, especially to the communications engineer!
The Disappearing Spoon sounds interesting
@jan. I think it's about warnings
The reason I ask about "The Disappearing Spoon" is that I'm currently reading the sequel -- The Violinist's Thumb (Click Here to see it on Amazon). This is all about DNA -- again, I'm learning all sort sof interesting "stuff"
@jack what was your last blog about again?
Tomii - I'd say that your blogs have done the opposite for me.
@tomii I suggest that all of you that suffer from insomnia should pay close attention to my own blogs - they're a good cure for that, I think.
I will take your advice.
Tell me more about system generator's stuff next :)
It's way over my bedtime over here
@jack: What I can write about now?
Don;t ask us -- tell us! :-)
I guess I need some sleep first :)
Did you ever read "The Disappearing Spoon" by Sam Kean (click here to see my review). This is a book about the elements -- I consider myself to be pretty "well read" (at a layman level) in things like physics, chemistry, and biology, but I learned the most amazing things in thsi book -- 100% highly recommended
@adam: Bye, Adam! sSee you next ...
What I can write about now?
I suggest that all of you that suffer from insomnia should pay close attention to my own blogs - they're a good cure for that, I think.
@jan probably not as max has back log of about 10 of my blogs but I will write the signal and variable one while I am away over the next few weeks
@Max I'm very proud on my next blog - unfortunately it's still "all in my head" :-)
@adam Here is my guess: your next blog will talk about register inferencing from variables. Right?
@Warren: You just need to always run a 42MHz...
GOOD ONE!!!! We shoudl create designs running at 42MHz without rtelling anyone why...
@jack Hi jack, rather the "HDL design done right" advocate :-)
@Jan: Be sure to check out my next blog, which will be called "Thinking software at the RTL level" :-)
Looking forward to it -- I always learn something uneful and interesting from your blogs
anyone know if the Virtex 7 is really shipping on any economical development boards? We have a project coming up and are seeing very long lead times.
@Duane: No douubt, sounds an awful lot like "shucks!"
Max- You just need to always run a 42MHz...
Haha the software advocate jan is here
"Frigus Fabam" sounds like a phrase that could be used in different circumstances than "cool beans."
Max- But what kind of beans do they mean in Latin?
@Max: Nope. It's for a Spartan6, and I'm using a Spartan3E. Dowsnot support.
Basically, I'm trying to generate 7 internal clocks for use in a variable-speed sampling circuit.
Speaking of switching clocks, though, the BUFG_MUX is a nifty little piece of hardware. I like how it ensures there's no glitches on the transition from one clock to the next...
@adam Be sure to check out my next blog, which will be called "Thinking software at the RTL level" :-)
Seeaking of Cool Beans -- you know how I often say "Cool Beans"? Well, I recently discovered that this is "Frigus Fabam" in Latin, according to Translate.Google.com
Simulink is kinda weird. I can't get what they are looking for when the error pops up
@jacklsw86 get max to put us in contact and I will send you a slide pack of how to use it from a company I used to work at
Max - I did not get to that one yet, but I'll have to check it out.
@tomii: ...I see a new blog on switching internal frequencies on the fly... I've been wrestling with this for 2 weeks, now...
So once again we see that All Programmable Planet has the answers to life, the universe, and everything!
@all right gents sadly I need to get going and go home it will be three weeks before I can join you again ;(
@rfindley, cool. I wonder if there's a good tutorial on Xilinx website or anywhere
Tomii - That blog looks pretty interesting. I'm not totally sure what I could use it for, but it's a fairly common things in the MCU, so I want to know how to do it.
@all - I sent that link to the Minecraft video to my 8 years old grandson's mother just because he wanted the LEGO version. Perhaps when he becomes 10 he will be hooked! What do you think?
Did anyone see my Gnarly to the Max blog on Programmable Logic Designline -- it contains links to three great videos / animations on YouTube -- Very "Cool Beans"
@rfindley: Better than it being for "backwash!"
Ack! I see a new blog on switching internal frequencies on the fly... I've been wrestling with this for 2 weeks, now (and all without knowing a thing about FPGAs, too!) I'll have to llok into that one. I got DCM's working, and then not, and then used home-made dividers to get where I wanted to go, but now that I'm adding in some pre-compiled IP, I'm getting messages that my clock isn't in the right quadrant. AAAAARRRGGHH!
@tomii/max, Maybe 'blog' is actually short for 'backlog'. :-)
Anyway, the backlog makes me feel a little better about taking extra time to really polish up my upcoming blog series.
@jacklsw86 yes I have a few years ago though now very powerful tool
@Toimii: ...Max is underpaid and overworked. (or is it the other way around?)
Nope -- you got it right :-)
@Max... We have lost a lot of good people over the last year due to lack of belief in development.
I am glad you had "wiser heads". We are beyond that....
... Well, that and Max is underpaid and overworked. (or is it the other way around?)
@jacklsw86, re:"System Generator". I've used it for Zynq and MicroBlaze.
@Rfindley: It's one of those games that will just suck your life away. It's why I haven't posted a blog recently...
@adam.. thanks for the kind words
Tommi - Minecraft is an amazing phenomenon. It's like virtual Legos on steroids.
@Tomii, re:Minecraft.... Thanks for the advice. There was a clone of Minecraft on the Amazon.com "free app of the day", and I was considering looking into it :-)
@marlowg:...things are a little tough as our R&D budget has been cut and we are going to loose people
I'm sorry to hear that -- I hate going through that -- I came close myself on occasion (before wiser heads prevaled)
Anyone tried using system generator?
@Max lol I will write the signals and variables ask adam over the next few weeks while away
Marlowg - I'm sorry to hear that.
PRO TIP: If you're even a little bit OCD (and you know you are, you're engineers and the like), then stay away from "Minecraft"
>.<
@marlowg sorry to here that
@adam... just whispering the word "variables" makes Jan's ears prick up...
Did you ever see that horror film "Candyman" where if you say his name three times in front of a mirror .... well, let' sjust say that you shouldn;t say his name three times in front of a mirror...
I dare you to stant in front of your bathroom mirror tonight and say "Variables" three times...
Adam - I look forward to reading that blog. As I said the thread was pretty much over my head, but as I was trying to interpret all of it, I learned a number of things that will help my VHDL adventures
Well, things are a little tough as our R&D budget has been cut and we are going to loose people. It's sad times...
@MAX - Thanks, my pleasure and honor.
@Max you should be so honoured, one day I will be knighted lol
@Jack" You are right -- the APP membership is growing in leaps and bounds
@Max, "august presence"... but be jet lag, because this is January ;-)
Duane it was I knew as soon as Imentioned variables Jan would comment on it.. but actually being fair I did not make it clear exactly waht I menat. So I will do a blog on it
Hi Marlowg -- how are things in your neck of the woods?
Thanks! I'm interested if there will be any comments on Open Sourcing FGPA Tools
@Adam -- we're just glad you coudl grace us with your august presence for even a few minutes...
I see the APP family is growing day by day
Hi Brian (Durwood) -- great to see you -- your next blog shoudl appear on the APP site in about 30 minutes
Adam, before you go - That was an interesting thread on my last blog. It's pretty much all over my head, but hopefully I'll understand some of it one of thes day. The NASA link was a good one.
Sadly I got no inspiration for now lol
Hi intseeker (a.k.a Luiz) -- it's GREAT to see you here
sadly gents I can only stay a few minutes tonight as need to go home lol
Jack -- you're back!!!
Someone was asking me the other day when we were going to see your next blog -- your public eagerly awaits...
Helloooooooo Eric the half-a-bee
Hi, Everyone! I am a new member and will already ask to bail out by 1:40PM EST for another meeting.
@Adam: It's not that Tomii iis keen -- just that he has no sense (of time :-)
Our weekly chat will commence at 12:00 p.m. my time (Central USA Time), which is 1:00 p.m. Eastern Time, 10:00 a.m. Pacific Time, and 6:00 p.m. UTC/GMT (you'll have to work out your local time from these clues -- or you can use this handy-dandy Time Zone Converter).
As always, we will be following our usual practice of leaping from topic to topic with the agility of young, fearless mountain goats, so make sure you're wearing appropriate clothing!

Today's FPGAs already integrate a substantial amount of "stuff" (MCU cores, programmable fabric, on-chip memory, etc.), so what's left to integrate and why is this being left for the future?
To celebrate Geek Pride Day, Sylvie Barak has created a mega-cool infographic that depicts how geeks have been building the Internet since 1832.
When traversing serial links with optics or backplanes, high-speed signals are degraded by impairments in the link, such as insertion loss, reflections, crosstalk, and optical dispersion.
Can statistical or heuristic verification really work for FPGA designs?
One of the things I've been wondering is whether or not the "okWireOR" module is really just a giant OR, or if the order in which things are attached matters.
