External Clocks used as the FPGA clock
@All

I shall shortly be trying to interface a simple FPGA design to the signals generated by an external micro.

This micro has a clock to which the signals bound to, so can i use the Micro clock for the FPGA ? or does the FPGA clock need to be specific to the FPGA?

Using the Micro clock on the FPGA  would to my way of thinking mean that the inputs are syncronized with the FPGA?

Does this proposed scheme have major problems, Micro Clock rate is likely to me no greater than IMeg Hz.

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.
I am shocked and horrified. It appears that those little scamps at Planet Analog are writing blogs pertaining to field-programmable issues.
