Quantus Error – Sky130 qrcTechFile not recognized as valid technology file

Hi all,

I’m setting up Quantus RC Extraction for the Sky130 (sky130_release_0.1.0) PDK, and I’m running into an issue with the provided qrcTechFile.

My environment:

• PDK: /class/ece482/sky130_release_0.1.0

• Quantus path: /class/ece482/sky130_release_0.1.0/quantus/extraction/typical/

• Cadence IC version: (please insert, e.g., ICADVM 23.1)

When I run Pegasus Quantus from Virtuoso and select:

/class/ece482/sky130_release_0.1.0/quantus/extraction/typical/qrcTechFile

I immediately get the following error:

Error: qrcTechFile is not a valid Quantus technology file

When I inspect the file using head, it’s clearly binary (starts with unreadable characters and the line:
CADENCE TECHFILE FORMAT openprocess (RC) (BASE) 21.2.2-p045 2024/2/26,...).

Can someone from Cadence please confirm:

1. Whether the qrcTechFile in this PDK is meant to be used as a Technology Library (compiled form) rather than a text tech file?

   If not, is there a plain-text version of this QRC tech file available for Sky130 academic installations?

2. Any clarification or working example would be greatly appreciated — especially since DRC and LVS (Pegasus) work fine in this setup, but Quantus extraction cannot proceed without a valid QRC tech definition.

   Thanks in advance!
