IBM 32 nm PDK transistor lengths not editable?

[xplorin]

I am working on IBM 32 nm soi process. The fet models available in the process have the 'length' field which is not editable. Can anyone help me with making the length fields editable.

thanks

I think - up to now - only for this very length there's a supported simulation model file available, so it doesn't make sense to change it. If you'd achieve to change it anyway, your simulation wouldn't work - or would provide too inaccurate results, if you'd change the length in the netlist.

Look for an alternate PDK mos primitive that isn't "digital" or "rf" -
these will tend to be fixed length in the interests of modeling
edgy performance. There ought however to be an "analog"
or "i/o" transistor type with parameterized L and not-as-good
high speed modeling. You'd think.
