Unrelated CI fail - the same as on the master branch |

@luarss Did you have a moment to take a look at this PR? |
@eszpotanski Yes, refactoring is a high priority item for AutoTuner as well. This is next after the smoke tests are merged. Also, could you possibly split this into 2 PRs - refactoring and new feature? |

This PR extends AutoTuner with a support for Vizier and a few of its multi-objective optimization algorithms. Which are better at finding valid parameters for hard-to-built designs.
It is based on #2487
Dependencies were separated into:
tools/AutoTuner[ray]- for Ray Tune,tools/AutoTuner[vizier]- for Vizier.Vizier and Ray Tune uses the same configuration scheme, but instead of combining metrics into one value, Vizier looks for non-dominated results (list of metrics). Apart from default metrics (like
total_power,worst_slackorfinal_util), a additional few had been added:clk_period-worst_slack- the difference between clock period and worst slack,last_successful_stage- artificial metric representing a number of the latest stage that was successfully build (help to find valid parameters),core_util- when floorplan fails (usually due to too largeCORE_UTILIZATION),core_utilmetric is multiplied by -1 to indicate that it should be smaller (helps to successfully built floorplan).Metrics can be chosen with
-mor--use-metricsargument.To speed up the optimization process,
--to-stageargument was implemented, which chooses stage (and its dependencies) that will be built. It's useful for user interested only in results from e.g. placement.--to-stageworks for both Ray Tune and Vizier.Instructions for preparing and running AutoTuner, as well as described arguments, can be found in InstructionsForAutoTuner.md
