. (As a rule, cells with "xres" in the name are found only in the xres I/O cells, and cells with "gpiov2" are found only in the gpiov2 I/O cell.)lukefahr

This probably works better on a flat netlist, although I have run it on a shallow hierarchy (standard cell layout) without issues. I am still working on a better solution that does not depend on the .sim file format (which is a flat format).Kunal

which now installs from the custom section of open_pdks. It is basically what I suggested, which is a power pad with the clamp circuit yanked out of it, and all metal removed from around the pad except for the pad ring busses. I threw a deep nwell under the whole thing for good measure. I have no idea if it will meet the 5GHz bandwidth requirement, but it is as much as I can do with relatively simple edits.Tom
