I am trying to simulate following the instructions in the pdf attached. But I keep getting the following error:
"Missing or corrupt .oa file in cellview 'cnt/nCNT/spectre cmos_sch cmos.sch schematic veriloga'. The OSS netlister can only process cellviews that have a valid .oa file. This file can be created by either importing the cellview using tools like 'Verilog In' or 'VHDL IN', or by opening and writing the text file in the Library Manager."
How do I solve the problem?
