@stevenmburns , this is where the Python placer is called. I am dumping pva just for observability. Its structure is as follows (truncated for readability):

{
  "leaves": [
    {
      "abstract_name": "NMOS_3T_85679509",
      "concrete_name": "NMOS_3T_85679509_X2_Y2",
      "constraints": [],
      "bbox": [],
      "terminals": []
    },
    {

      "concrete_name": "DCL_PMOS_2T_69165982_X2_Y2",

      "bbox": [],
      "terminals": []
    }
  ],
  "modules": [
