 		 #114411 - FPGA libraries in general
Responding to: ???'s previous message
Richard Erlacher said:
Of course, finding the component you want in PCAD is tricky, mainly becuase their libraries are vastly out of date. Last time I looked, the latest XILINX components in their libraries had been out of production for a full decade.


My preference when doing schematics is to use application-specific symbols for my FPGAs. I'd rather break the symbol up into several logical parts (PCI interface, back-end interface, this, that, the other) instead of having a page with a big symbol in the middle with 256 (or more) wires going every which way.

Obviously, this requires a custom symbol, and worse, it's a PITA if you change the pin-out, but everything's a trade-off.

               Yes, about five IC's            01/01/70 00:00      
                  OK, now it makes sense            01/01/70 00:00      
                     Well, how would you do it?            01/01/70 00:00
