Issue with Impedance/Reflection Analysis in Sigrity Aurora 23.1

Hello Cadence Community,

I am using Sigrity Aurora 23.1 and while performing reflection and impedance analysis, the error log initially showed:

The database version of the design file is not compatible with the Sigrity release version that is currently installed. Refer to the Compatibility Matrix section of the Installation Guide for information on the compatible Sigrity release version.

To resolve this, I installed Hotfix 2, which is compatible with Sigrity Aurora 23.1 and PCB Editor 23.1 base version.

My board design was originally done in Allegro 17.2, so I:

1. Saved the board in PCB Editor 23.1,

2. Then opened it in Sigrity Aurora 23.1.

After installing Hotfix 2, while simulating the analysis, the database compatibility issue was resolved, but a new problem arose:

invalid command name "sigrity::selectnet"

The net selection workflow seems to be working as expected, but this message still appears in the log and may be affecting the analysis.

Could someone guide me on:

• How to handle this sigrity::selectnet issue in HF2, & complete the simulation.

Any suggestions or workarounds would be highly appreciated.

Thank you!
