Code Review
This pull request introduces timing-driven macro placement by integrating the Resizer module to identify critical nets. The changes consistently extend the existing simulated annealing algorithm to incorporate critical wire length into its cost function. The modifications span across various components, including the MacroPlacer initialization, CMakeLists.txt for linking, header files for new methods and members, and source files for implementation details. The Tcl interface has also been updated to expose the new timing_driven option. The changes are well-contained and appear to be functionally sound.
