What family of xilinx was that part? Was it a compiler issue or a die problem? I guess I'd be gunshy after something like that; but isn't it sort of like abandoning all the microchip product line because of the now famous 18F1320 clock problem? Not a critique, I'm sort of that way with motorola after some parts allocation problems. > Theoretically CPLD are marvelous devices, but when there is a problem > inside, physically moving San Francisco a foot further to the left is > easier... That might not be quite so difficult; just wait for the next big quake and have nature do it for you. :') -- http://www.piclist.com hint: To leave the PICList mailto:piclist-unsubscribe-request@mitvma.mit.edu
