- Added APB target definitions in soc_topology.json for various peripherals. - Introduced user_extensions.json to define user core and IP targets. - Updated generate_filelist.py to include SVA paths. - Refactored ip_apb_wrapper.sv to utilize generated APB interfaces and bridges. - Simplified user_core_top.sv and user_ip_top.sv by including generated bindings. - Implemented check_clock_reset_domains.py to validate clock/reset domains and CDC crossings. - Updated regress.py to include SVA support in simulation commands. - Added tests for clock/reset domain validation and user extensions generation. - Enhanced test coverage for topology generation and APB target ownership validation.
