Computer Architecture (Logisim)

Model the designed 32x32-bit register file as one single module in logisim and test the register file for correct operation by writing to and reading from different register combinations.

-BusA and BusB: 32-bit data output busses for reading 2 registers. During read operation, the register file behaves as a combinational block and once the RA or RB have valid data, the content of the read register will appear on BusA or BusB after a certain access time.

-RegWrite: control signal to enable/disable register writing operation. When RegWrite is 1, register write is enabled; otherwise, is disabled.

-BusW: 32-bit data input bus for writing a register when RegWrite is 1

-RA: 5-bits selection lines to select the register to be read on BusA.

-RB: 5-bits selection lines to select the register to be read on BusB

-RW: 5-bits selection lines to select the register to be to be written with BusW.
