Synopsys Star-RCXT Problem

[letitwork]

Hi all,

We are trying to run Star-RCXT on a mixed-signal layout that includes digital standard cells that we are not provided full layouts for. i.e. the poly layer is missing.

We want Star-RCXT to just ignore the standard cells but it isn't working. This is preventing Star-RCXT from successfully extracting and back-annotating our design. In Star-RCXT, I have set the "SKIP_CELLS" command appropriately, but the report file says:

****
WARNING: SKIP_CELLS list member "std_cell_no_poly" is not an equivalence point and will be ignored.
****

The resulting extracted netlist is has flattened the standard cells and is missing the digital transistors. Has anyone else ever seen this? Any ideas how to fix it? Thanks so much in advance!

Are you using Calibre LVS device-Extraction (output should be AGF) or you are using Hercules LVS for the device-extraction. ( output XTR View MW).

What I mean "extraction" here is device extraction to create annotated databases ( including LVS ). Not the parasitic extraction.
