Pfet pcell don't generate preview box #42

Open akiles-esta-usado opened 11 months ago

akiles-esta-usado commented 11 months ago

Expected Behavior

When trying to instantiate a pfet pcell it should give a visual guidance of empty polygons.

Actual Behavior

The first time a pfet is placed, it shows nothing. Modifying the pcell fixes it.

Steps to Reproduce the Problem

To reproduce this problem we use this docker container created by our team. It has gf180mcuC configured as default PDK, with all the changes recommended on the youtube video.

  1. Open klayout -e and create a new layout
  2. Instanciate a pfet pcell on the layout. It shows nothing.
  3. Go to Pcell tab on Editor Options and change any parameter (Tested with Deep NWELL and number of fingers).
  4. Now the pcell is visible.

Specifications

Specs Value
PDK gf180mcuC

New discovery

Using PDK gf180mcuD and gdsfactory=7.8.16, changing pcell parameters don't fix the problem, just makes pcell crash. I've install the new gdsfactory version with pip install gdsfactory[cad] --upgrade.

@FaragElsayed2 I believe that's a klayout issue not the PDK. Could we please give it a try and see if we have this same behavoir at our end on our ubuntu 22.04 installation?
