Title: Cadence Layout Cannot Show PDK Instance Graph
Post by ovicovic on Jun 8^th, 2022, 9:06pm

1. Configuration: Cadence IC617 + MMSIM151 + Calibre 2015.
2. PDK: TSMC CRN65GP, install using pdkInstall.pl in PDK.
3. I am studying the LNA tutorial given by TSMC docs. The schematic simulation is fine. But in the layout, the Instance in the PDK library is not displayed, just a transparent box, after press "shift + F", the box like this "☒". If I add Instance in my Library, an error will pop up.
--------
CDF: An error occurred when evaluating callback.
Callback: m->display => iPDK_isSchematic()
Message: *Error* eval: undefined function - iPDK_isSchematic
CDF: An error occurred when evaluating callback.
Callback: mismatch->display => iPDK_isSchematic()
Message: *Error* eval: undefined function - iPDK_isSchematic

4. Open the layout of Cell nmos_rf in the PDK Library, there is a warning prompt, but the layout is displayed normally, with colors and layers.
*WARNING* (DB-220704): The Pcell super master: TSMC_CRN65GP/nmos_rf/layout is not s SKILL super master. The usage of non-SKILL Pcells in virtuoso is not a supported feature.

This is best taken up with TSMC, but I think you need to install the SKILL flavour of the PDK - it looks as if you have a PDK version intended for non-Cadence tools installed, and so the callback functions are missing and it includes non-SKILL PCells.

Also, is there a good reason why you'd be using such old versions of the software (IC617 is no longer supported, and you're trying to use a 7 year old version of Spectre).
