- Updated soc_topology.json to include new fabric links for core, DMA, native, and APB interfaces. - Refactored retrosoc.sv to utilize generated fabric links and included necessary SVH files for better modularity. - Improved check_clock_reset_domains.py to validate hierarchical pins and added support for positive number checks. - Modified regress.py to include OpenSTA in the regression commands. - Enhanced README.md in the STA directory to clarify the timing analysis flow and supported PDK profiles. - Removed outdated gen2.sdc file and replaced it with a dynamic SDC generation approach. - Updated opensta.mk to generate SDC files dynamically based on the current domain map and pin map. - Created generate_sdc.py to automate SDC generation from clock/reset domain inventory. - Added tests for generated core-STA constraints to ensure coverage of current clock domains and validate pin map integrity. - Introduced new timing metrics and warnings for the sky130 PDK in the quality checks.
