Title: Star RCXT issue with standard cells
Post by bugmenot on Feb 15^th, 2008, 2:39pm

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 flattens the standard cells and is missing the transistors. Has anyone else ever seen this? Any ideas how to fix it? Thanks so much in advance!
