Describe the bug

I have created a project using picosoc and added I/O PADs similar to the i2c-gpio project. During the "make cts" phase there is a segmentation fault and the proces stops. Changin the constraints to a lower clock passes and the desing can get to the end of the process.

Expected Behavior

The cts step is able to finish.

Environment

Using docker image with commit 6f51ec8c93e1edeb3be4d2747894fd28f711f28f

To Reproduce

cd flow export DESIGN_CONFIG=./designs/ihp-sg13g2/picosoc_ihp_test/config.mk make synth make floorplan make place make cts
