Hi! You need to look in `06-yosys-synthesis` for the Yosys log. The checks are running in a later step.

if it begins with "yosys" it's a yosys pass, if it begins with "checker" it's not a yosys pass

OHHH alt thx I'll look into it!!

(Leo's a LibreLane maintainer, and I'm a Yosys dev, so we'd both be happy to help with issues you might have)


[2026-04-16 11:02 a.m.] dorythecat_v2
Oh that's so awesome! Very glad to have you helping! <3


[2026-04-16 11:03 a.m.] dorythecat_v2
I'll let you both know what the issues were and if I managed to fix them or need a hand with em lol

This is the log. It seems to complain about the bidir configuration???

Any clues on waht the fix might be? It says multiple conflicting drivers :(


[2026-04-16 12:07 p.m.] dorythecat_v2
According to this it's becaue I'm using the register in multiple places? huuuuh


[2026-04-16 2:42 p.m.] ravenslofty
no, it's not that you're *using* it in multiple places, it's that you're *driving* it in multiple places


[2026-04-16 2:43 p.m.] dorythecat_v2
fair


[2026-04-16 2:43 p.m.] ravenslofty
librelane should lint your code with Verilator - `01-verilator-lint`; what does it have to say


[2026-04-16 2:44 p.m.] dorythecat_v2
Turned up being that I was doing:
```
...
s0 <= bidir_in;
s1 <= bidir_in;
...
```


[2026-04-16 2:44 p.m.] ravenslofty
that shouldn't cause issues.


[2026-04-16 2:44 p.m.] dorythecat_v2
Upon removing it the issue stopped showing up


[2026-04-16 2:45 p.m.] dorythecat_v2
Rn I'm just testing my workflow but if this comes back to bite my ass I will lyk


[2026-04-16 2:45 p.m.] dorythecat_v2
-# I just want to make sure I can generate the silicon and goddamit is it not wanting to 😭


[2026-04-17 5:20 p.m.] dorythecat_v2
@Lofty mind if I share my code with you? I updated it and it is back to causing "multiple driver" issues xd


[2026-04-17 5:20 p.m.] ravenslofty
Sure.
