- Updated README.md to clarify the status of KianV RV32IMA and PicoRV32 in the user-extension map. - Modified Makefile to include USER_EXTENSIONS_SOURCE in MPW variant stamp dependencies. - Enhanced integration README.md to better describe the relationship between user_extensions.json and mpw.toml. - Updated generate_user_extensions.py to include design_id in ExtensionTarget and enforce unique design IDs. - Changed user_extensions.json schema version to 2 and added design_id fields for core and IP targets. - Refactored generate_mpw.py to support the new manifest structure and validate design selections. - Adjusted sysctrl_tb.sv test cases to reflect changes in user core reset states. - Enhanced test_opipsram.py to utilize ccache for improved compilation performance. - Updated test_script_tools.py to include new tests for active manifest generation. - Modified test_user_extensions.py to validate isolated scalar bindings and reject duplicate design selections.
