Hello everyone,
I am having an issue with (at least the display and simulation) of a newly added library in Cadence. I was using the regular 180nm General Purpose PDK from TSMC, listed as tsmc18 on my system. I would like to use their BCD process. So I have added to my cds.lib file the line DEFINE tsmc18_BCD /path_to_the_PDK, and I can properly see that newly added library under the name tsmc18_BCD in my Library Manager.
I can see all the devices, but when I want to look at a device (layout, schematic, symbol...), everything appears as yellow. So it seems that, at least my display parameters are broken (but I believe it is a symptom of a larger problem). When I create a new working library that I attach tmsc18_BCD as technology library to, I cannot run any simulation, I get the following error message:
Error found by spectre during circuit read-in.
ERROR (SFE-868): "input.scs" 9: Cannot open the input file '/path_to_tsmc18_and_not_tsmc18_BCD/../models/spectre/c018bcd_gen2_v1d6_usage.scs' because either the file name or the directory specified is invalid. Ensure that the specified file exists and the path to the file is valid. Alternatively, use the -I <path> command-line option to specify the path to the file and rerun the simulation.
If I attach to my working library the tsmc18 technology library, then schematics are displayed properly, but I get the same error when trying to simulate.
I guess I understand that Virtuoso is looking for BCD models in the other library, meaning that my tsmc18_BCD is not properly added to Virtuoso. So, I understand that adding just a line to my cds.lib file was not enough to be able to use correctly this library. Could you help me figure out how to properly tell Virtuoso how to use the tsmc18_BCD library?
Thank you very much in advance!
