riley 900b544bc6 Added python script for invoking icarus verilog. This script has three subcommands; submit, test_submit and test. test is equivalent to the run.bat shell script, submit generates a single-file verilog source suitable for submission. test_submit will run all generated submission testbenches to verify that nothing was broken. 
Renamed submission folder to fix typo.

Merged incomming changes
 2026-09-15 21:29:54 +10:00
riley 392f1f7a27 Updated shifter testbench to work with 2^n widths rather than bitwidths. 2026-09-15 21:29:47 +10:00
riley 287fc1903d Updated default ASU testbench width to be 4-bit to align with seven segment width for demo 2026-09-15 21:28:01 +10:00
riley 19cd7ac177 Updated ALU and ASU modules to conditionally require seven-segment output logic. Used for the assignment 1 demo and MUST be stripped for assignment 2. 2026-09-15 21:27:04 +10:00
riley c4ebde7692 Updated ASU to use an explicit MUX rather than the XOR inversion 'trick' when calculating the operand 2026-09-14 00:13:17 +10:00
riley 4df723318b Ensured case variable assignment is internally consistent with other possibilities to ensure optimal case synthesis 2026-09-13 23:53:47 +10:00
riley 49f539c855 Updated instruction classifier to use combinational logic with a depth of 3 gates (AND, XNOR, HAND) 2026-09-13 23:35:05 +10:00
riley 19ba1bf473 Added header guards to prevent errors from double-inclusions 2026-09-13 23:09:08 +10:00
riley 78efccfe1e Implemented ALU test cases for all operations. Added ALU testbench to active testing. Fixed bug where alu_flags module argument was defined as a 2-element logic array output rather than a 2-bit logic output 2026-09-13 23:08:07 +10:00
riley f69f87ccab Just add cases for ALU testbench. The structure of the ALU testbench is now implemented. 2026-09-10 15:57:56 +10:00
riley cd7074a78c Need to change instruction classifier implementation to use a more parallel architecture as case statements can produce sequential MUX'es 2026-09-10 15:56:59 +10:00
riley 37644c629e Fixed bug of confuddling width with 2^n and w. 2026-09-10 15:42:50 +10:00

riley 5acf1c8b87 Fixed bug in adder/subtracter where code assuming width was the bit width was not updated when moving to the 2**N approach required by the assignment.

riley f5a2455849 Added testbench for instruction classifier and fixed compilation errors. Should be fine to synthesise but icarus does not like the constant bit extraction in the always_comb block for some reason. 2026-09-08 21:31:18 +10:00

riley a89a66d34d Fixed bug where includes still refered to verilog rather than systemverilog. Inverted test cases in seven segment test bench to reflect changes made to module. There is still a bug with the module where it outputs garbage 2026-09-03 16:32:56 +10:00
riley f881a4126b Inverted seven segment decoder to reflect the common anode 2026-09-03 16:27:01 +10:00
riley 6668969b03 Made it clear that we are using SystemVerilog by renaming HDL files to end in .sv rather than .v 2026-09-03 16:05:52 +10:00
