[SUPPORT] RuntimeError on ws.db.save

[leochand101]

Describe the bug RuntimeError: ("putprop" 0 t nil ("*Error* putprop: first arg must be either symbol, list, defstruct or user type" nil)) while running ws.db.save

To Reproduce ws.db.save(cell_dict[topcell]) I am passing a cellview_pointer to it

Expected behavior The command clearly works as the schematic is saved but then the return value has some issues, I believe its expecting

Error Stacktrace Response is ("putprop" 0 t nil ("Error putprop: first arg must be either symbol, list, defstruct or user type" nil)) Status is failure Traceback (most recent call last): File "/home/<>/scripts/Query_cadence.py", line 287, in set_width("w", "500n", cell_comp_dict, topcell) File "/home/<>/scripts/Query_cadence.py", line 236, in set_width ws.db.save(cell_dict[topcell], cell_dict[topcell].lib_name, cell_dict[topcell].cell_name, cell_dict[topcell].view_name) File "/home/<>/.local/lib/python3.9/site-packages/skillbridge/client/functions.py", line 41, in call result = self._channel.send(command) File "/home/<>/.local/lib/python3.9/site-packages/skillbridge/client/channel.py", line 158, in send return self._receive_only() File "/home/<>/.local/lib/python3.9/site-packages/skillbridge/client/channel.py", line 154, in _receive_only return self.decode_response(response) File "/home/<>/.local/lib/python3.9/site-packages/skillbridge/client/channel.py", line 48, in decode_response raise RuntimeError(response) RuntimeError: ("putprop" 0 t nil ("Error putprop: first arg must be either symbol, list, defstruct or user type" nil))

Additional context Save happenend succesfully but the return value evaluates to failiure. Not sure if I am using it wrong or not because the cell was saved.

Unfortunately i cannot reproduce your error.

This code works for me:

from skillbridge import Workspace

ws = Workspace.open()

c = ws.ge.get_edit_cell_view()
assert c is not None

print(ws.db.save(c, c.lib_name, c.cell_name, c.view_name))  # True

Are you sure that cell_dict[topcell] is a valid <remove cellView@...>? Can you show the contents of that cell_dict and also the values lib_name, cell_name and view_name.

Another idea: Did you call the function putprop anywhere? Maybe you ran it directly in the CIW.

Ok I see what you said here, I did change some cell masters using replace_any_masters and hence the pointer to the cell is no longer the same I needed to open the modified cell again using ws.db.open_cell_view which returns the updated pointer and that saves fine!!! Thanks @nielsbuwen Solution for anyone ever encountering this error, reopen the cell in question again after modification to save it successfully :

Can you update the label from BUG to SUPPORT @nielsbuwen ?
