Matt Liberty · Answer

are you reading in the verilog or just the DEF

Matt Liberty · Answer

the escaped name in verilog microwatt 0 soc0 processor register file 0 register file 0 probably requires some escaping when passed to read spef otherwise it will interpret the as hier delim

Anton Blanchard · Answer

I did think it could be that and tried various combinations like ` microwatt 0 soc0 processor register file 0 register file 0 ` but haven t found one that works yet

Matt Liberty · Answer

I can see from your read lef that you are running this in openroad You need to run it in standalone sta OR doens t support verilog hierarchy but sta does

Matt Liberty · Answer

sta sta tcl gives no read spef errors for me
