Looking for working crc32 code in C or Verilog

crc32 behavoural

I've designed a 10/100 mac and am currenly trying to verify it. I want to perform the crc at a higher level of abstraction to test the combinatorial logic for the crc. I know the crc logic is good cause i've used example frames i've found. The problem though is i would like to not have to use the combinatorial in the testbench.. but i am having a hell of a time finding any crc32 code (c or otherwise) that will create the correct crc.

Does anyone happen to have some known working crc code in c or verilog or whatever that i can try?

I've tried a bunch of c ones online but none of them even create the same crc that the example packet they came with uses.. I've tried inversion and reversing, swapping nibbles, etc.. no luck

thanks!

p.s.
for getting real Ethernet pacpacket for testing, you may use Ethernet sniffer, for example free Etherreal:

and real packet samples:
