Cannot abut devices in Layout XL, tsAbutFunction failed.

imcostanzo

Hello,

I am trying to abut devices in Layout XL. In the past, I have been able to either use the Chain Devices dialog available in the connectivity drop-down menu or by simply placing devices that share the same net on top of each other. However today I can't seem to do that. I get a warning that the function tsAbutFunction failed.

This is from the CIW:

*WARNING* (LX-2205): Unable to abut the following two instances:
 'M9.1' (instance of cell 'nmos2v')
 'M9.2' (instance of cell 'nmos2v')
This occurred because the abutment function (tsAbutFunction) failed
when called to adjust pcell parameters for abutment (event 2).
INFO (LX-1100): Correct tsAbutFunction and try again.
INFO (LCE-1007): The cell verifier found
INFO (LCE-1008):    671 open(s)
*Error* fix: argument #1 should be a number (type template = "n") - "iPar(\"simM\")"

Searching for tsAbutFunction doesn't turn anything up and I didn't find any information or fix in the Abutment documentation. Has anyone ran into this issue before?

Thanks,

Ian

    Ian,

    The abut function will have been defined as part of your PDK, and so tsAbutFunction will have been written by the PDK provider (probably). Without seeing that, I can't comment as to what might be wrong, other than the fact that it's clearly expecting something to be a number when it is not.

    I found some reports with similar messages - but they were quite old and so I'm not sure they are definitely the same cause (and even so, I think it was a PDK issue). Best to contact customer support so we can debug properly.

    Andrew.
