How to run the regression test suite for Ibex design verification?

Nobody has claimed this yet.

Dears,

I am trying to run the nightly regression for Ibex with iterations=1 for each test.
I want to check if the regression will pass or fail after making local modifications.
Also, I want to check if the issue is due to my setup or a specific commit from before.

Is there any script that you are using to run this regression?
I checked the documentation in [Verification - Ibex Documentation](https://ibex-core.readthedocs.io/en/latest/03_reference/verification.html#verification), but I am not sure if it is up to date or not.
Is there any history for the previous regression runs as well? similar to the latest that can be found here [Ibex Regression Results](https://ibex.reports.lowrisc.org/opentitan/latest/report.html)?

**EDA tool and version:** Questasim 2020.1

**Operating system:** Linux-64 CentOS 7.9

**Version of the Ibex source code:** df88055aa38868451ce90d7fcc2bbf172a2dc8a0

Start with the linked Verification - Ibex Documentation section and compare it with the requested nightly regression workflow using iterations=1. Check whether the regression script and historical results are documented; done means the current procedure and available run history are clearly identified or the documentation gap is recorded.
