But when i tried to read pdks/gf180mcuC/libs.ref/gf180mcu_fd_sc_mcu7t5v0/lef/gf180mcu_fd_sc_mcu7t5v0.lef this file, theere is unknown reference of site GF018hv5v_mcu_sc7. Can you please tell me why is this happening?

1 year ago @kareefardi Thank you, I understood. Now the tool is reflecting syntax errors while read_verilog for any verilog file I try to read even when the flow has completed successfully. Is there any solution or is it a bug? Please let me know.

1 year ago openroad> read_verilog designs/picosoc/src/picosoc.v [ERROR STA-0164] designs/picosoc/src/picosoc.v line 80, syntax error, unexpected ID, expecting '=' STA-0164 while evaluating {read_verilog designs/picosoc/src/picosoc.v }
And the related line in the verilog code is: parameter integer MEM_WORDS = 256;

1 year ago @akhilesh911 you can only read a gatelevel netlist (not the src verilog) through OpenROAD app. Can you open a new issue describing what you are trying to do in order to get proper help?
