- Introduced sysctrl_define.svh to define register offsets and constants for SysCtrl. - Created sysctrl_if.sv interface for communication with SysCtrl. - Implemented sysctrl_reg.sv module to handle register read/write operations and state management. - Developed sysctrl_tb.sv testbench to validate SysCtrl functionality, including lifecycle, fault handling, performance monitoring, and RTC wake status. - Added Python regression test (test_sysctrl.py) to automate SysCtrl verification using Icarus Verilog.
