- Removed CORE and IP variables from common.tcl and synth.tcl scripts. - Updated yosys.mk to exclude CORE and IP from environment variables. - Modified bus_fault_tb to enhance NMI interface with management and user NMI signals. - Added user access denial handling in bus_fault_tb. - Updated pll_ctrl_tb and sysctrl_fault_tb to reflect changes in NMI interface. - Adjusted test_gpio_user_mux.py to remove IP_MDD definition. - Enhanced memory map tests to include user extensions and ensure proper generation. - Updated test_script_tools.py to reflect changes in core management and user extensions. - Refined topology tests to ensure user APB target is always added. - Adjusted tech cell configuration tests to use simplified profile paths. - Improved user extensions tests for scalar bindings and slot validation.
