I was attempting to run a GL simulation on one of my macros that uses the low-speed libraries. I know there is a GL sim issue with caravel at the moment, but the simulation was complaining that it could not find any of the _ls standard cells. I'm looking an dlooking but I can't figure out what's different between the paths for the _hd cells vs the _ls cells. Any thoughts? Anyone else try this?

I think the issue is that OpenLane support only includes the

hd

and

hvl

libraries. The file you're looking for is

caravel_netlists.v

and has the includes for those two libraries and none of the other digital libraries. You'd want to add the

ls

library there (this is in the path

verilog/rtl/

).

Thanks Tim. That's very eye-opening
