Re: [Iverilog-devel] How to debug the iverilog grammars?

[<ca...@li...>]

Thanks guys for the replies.

Yes I was looking for a way to activate the parse tracing features as
explained here : https://www.slac.stanford.edu/comp/unix/gnu-info/bison_11.html .

I have looked at the parse.output file that is generated but it shows the whole
autamata which is very confusing (im extremely inexperienced with bison) whereas
I would rather like to see the exact path the parser has taken at runtime, what tokens
were encountered and what tokens where expected.

>From my understanding the parse trace functionality if enabled correctly should show me
the exact states that were followed before my syntax error occurs.

For our project I hope to add multi-state UDP tables into a branch or fork of iverilog to allow
more concice gate-level RSFQ logic descriptions. I could share the git diff if anyone is interested.

Kind regards
Calvin
