18:20 <tich> Good day. I am new to developing gateware with amaranth-lang. I want to create a parallel CRC module as described in the article by Evgeni Stavinov http://outputlogic.com/?p=158. Is it possible in amatanth-lang to create a module that takes the generator polynomial and width of the message as parameters?

18:20 <agg> tich: yep, see https://github.com/amaranth-lang/amaranth/pull/681 for an example

18:21 <agg> (feel free to just copy that, too, if you just need a crc rather than implementing one for fun/learning/interest)

18:21 <tich> agg: thanks I will have a look

18:22 <agg> that one uses essentially the same technique as the article you linked

18:22 <agg> but has a little extra code to handle reflecting input/output, xoring output, comparing residue to check codewords, etc

18:23 <agg> which is to say: if you just need a totally standard crc and just want polynomial-in and crc-out, you could do it in less code, and certainly it's possible in amaranth

18:23 <agg> check out https://twitter.com/HarmonInst/status/1232036641616744448 for a smaller/simpler example

20:01 <mithro> undulate (a Python renderer for the wavedrom format) recently added console rendering output -> https://github.com/LudwigCRON/undulate/issues/35#issuecomment-1037193151 which could be useful for amaranth in some way?

20:02 <mithro> People might also find the unrelated https://github.com/pieter3d/simview which seems to be a console based tool for VCD / FST file viewing
