For a design with openram sram macros, how do you include the .libs? Aren't these needed to for STA?

I haven't found a place that OpenLane uses these...

Isnt that strange? These files should be needed to evaluate timing around the macros?

Yes it's very strange
I also haven't spent (any) time on it

Was timing not an important consideration in the SRAM test chip?

No, it's a test chip so we didn't even characterize all the memories
The goal was functionality of many configs

They are needed if you have any timing requirements on your rams - which you are likely to have.

Could you point to any resources or examples showing how to do this in openlane?
