I have the following question.
I updated our pdk (tsmc process) with some addons for rf devices and minor techlib tweaks.
We have some special capacitors (crtmom). The pcell for this is working good, but
if I open an old layout with pcells from before the chance I miss some layers (VIA2 and MET2).
The strange things is this:
In the same layout I have both types of the layouts (created by the pcell before and after the change).
1) copying/editing the new one all is correct, also if I insert it from the techlib as a new part.
2) copying/editing the old oneit still have the old layout (without MET2 / VIA2) inserting a part again from the techlib (the same cell as in step1) it comes with the wrong layout (without MET2/VIA2)
copying cell to another cell with different name doesn't help.
that means replacing hierachical is not working.
Any ideas how I can virtuoso force to use the correct pcell?
Thanks in advance.
