riley fe53955748 Fixed bug in test code where there was a hazzard, despite testing assuming no hazzard. Updated testbench to reflect this (Ln57-62). 
Added mem[0x000] to log message when printing registers.
Replaced 8 delay with explicit 5x 2 delays. (NOTE: Needed an extra one for ensuring write-back when comparing results.
Fixed bug where the wrong registers were being added together when creating the comparison point in the testbench.
Fixed testbench bug where S4 was checked twice and S5 not checked at all.
Updated display message on test failure to reflect that it is the pipelined version, not the single-cycle.

riley 38fa35fccd Fixed initialisation bug and compilation error in gatereg module. Added mips_pipelined to test suite. Fixed several bugs in assignment3 MIPS module 2026-11-05 14:10:13 +11:00
riley 704286f0e6 Renamed MIPS test to be a single cycle test 2026-11-04 15:42:52 +11:00
riley b52f01c3be Added some delay to better test final branch/halt. 2026-10-20 16:02:40 +11:00
riley 2f652705cc Fixed timing in testbench for branch iteration. 2026-10-16 12:51:21 +11:00
riley e7fff9f3dc Added explicit rst input to RAM and PC as well as the MIPS processor. 2026-10-16 12:11:19 +11:00
riley 559ff01d69 Fixed printing annoyance. Added variable dumping to a wavefile. Updated delay to 2 units (as there is 1 unit of clk being high and 1 unit low). 
Removed register initialisation code from testbench.
Fixed typo when wanting to check T0 (R8) but was checking R0.
Added explicit if-else begin-end blocks to logging and a simulation exit when the testbench is done.

riley 19e5843d55 Added testbench for MIPS processor 2026-10-16 03:53:14 +11:00
riley 1e13de9301 Updated assignment2. Created file for testing R-type instructions, still needs to be implemented. Consider using bind to be able to extract inner-scoped variables out for inspection. 2026-10-13 22:26:52 +11:00
riley 75ef513efa Added zero flag to ALU and updated testbench to not fail because of it. TODO: Add cases to test the zero flag 2026-10-13 21:34:25 +11:00
TroubleElectrical 56ade6b426 Added comments to Logic Unit (Q2) and added to submission file 2026-09-16 12:38:06 +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 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 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 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. Updated adder/subtracter testbench to correctly instantiate the asser/subtracter and removed unused variable 2026-09-08 22:49:22 +10:00
riley 42f4e661dc Implemented shifter and its test bench code fully 2026-09-08 22:35:14 +10:00
riley 9794f26137 Fixed error in logic unit testbench where it didn't instansiate the DUT at all as well as some faulty test cases and reset logic 2026-09-08 22:00:07 +10:00
riley fabfba7bdd Removed debug statement from instruction classifier testbench 2026-09-08 21:44:36 +10:00
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
TroubleElectrical 60e5dae43b Added ModelSim folder (and have to add files into it as to allow for different testbench code) 2026-09-08 16:32:01 +10:00
riley b926d71523 Updated seven segment test bench to reflect prior commit 2026-09-03 16:58:11 +10:00
riley dd5d044da3 Fixed bit ordering in seven segment truth table and test bench 2026-09-03 16:49:46 +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 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
riley 0c21734447 Created general project structure. Only seven segment, logic unit and adder/subtractor modules and tests implemented 2026-09-03 15:25:07 +10:00
