@eder-matheus what is the status here?

This is ready to merge. I think we forgot it between the other tasks. I'll just solve the conflicts.

There are test failures that need fixing too

Has this been through secure CI?

@maliberty This branch has two failures in the public-ci: ibex asap7: [ERROR] cts__design__instance__count__hold_buffer fail test: 15.0 <= 10.0 microwatt sky130hd: [ERROR] finish__timing__drv__max_slew_limit fail test: -2.0299 >= -1.58

However, the secure-ci is green, with a great improvement in ca53. The detailed route ends with 26 iterations, while in the master branch it ends with 50 iterations.

I don't understand why we have more cts buffers yet. I imagine that the global placement changed a lot due to the new groute resources. And if I remember correctly, the slew metric has a lot of noise. Should I investigate deeper these two failures, or can we just update these metrics?

Updating is fine. ca53 is great!
