get_pins segfaults with non-string property as filter #36

Closed gadfort closed 5 months ago

gadfort commented 5 months ago

The issue I'm running into was trying to find the register_clock pin on a cell. So there might be two issues going on:

  1. when calling get_pins -of_object $cell -filter is_register_clock==1 the tool segfaults (see the attached test case).
  2. non-string values such as is_register_clock is not meant to be supported by -filter, if that is the case, I think it would be a nice enhancement, if possible?

Test case: test_pin_filter.tar.gz

tar xvfz test_pin_filter.tar.gz
cd test_pin_filter
sta test.v

It should output:
