06/21/2021, 10:57 PMWe usually add a wrapper around the RAMs in other nodes. The wrapper scripts needs to be modified to work with openRAM. Are you aware of any wrapper in openlane?

06/22/2021, 12:01 AMthe wrapper is used to provide extra space for TR to rout to the pins (we used that in a finfet technology to avoid DRC errors)
