I have installed NCSU FreePDK45 design kit for Cadence IC615 but have problem instantiating device layout with the following warning.
*WARNING* (DB-220704): The Pcell super master: NCSU_TechLib_FreePDK45/nmos_vtl/layout is not a SKILL super master. The usage of non-SKILL Pcells in Virtuoso is not a supported feature.
I can only see a white box with cross of the device instance in layout but when I open the layout view of the device itself, it is visible with correct metal layers.
I followed the Setup Files section of the following link to install the kit with correct paths:
and for P-Cells I have installed 64-bit PyCell Studio from Synopsys using instructions from the following link:
I am using bash instead of cshrc shell and assume that the instruction: "Create a modified setup script for Cadence Virtuoso that includes PyCell studio" means the environment variables need to be set in .bashrc file instead of creating a .cdsinit file?
I do not understand what I am missing and why it is not working. Please help.
