Hi @amichai-bd ,

WIP: #652 :

In the past week, I made some progress on the ex_core project.
Key updates:

• Added a new RF block to the ex_core, along with its corresponding testbench. The testbench verified correct read/write operations to the register file, with zero errors and warnings.
• ALU opcodes were packed into an enum in the ex_core_pkg.sv file, and the ALU module was updated to use these opcodes. The ALU testbench was aligned with the updated opcodes, ensuring the ALU's functionality through random test cases.
• Additional housekeeping tasks were completed, such as cleaning includes and adding guarding macros to the macros file.
