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 e9feb3cb8d Merge branch 'main' of ssh://git.rileyk.au:19482/TroubleElectrical/FPGA_Uni 2026-09-10 15:38:50 +10:00
riley 669357ccc0 Implemented ALU. Still needs testbench and testing done. 2026-09-10 15:38:36 +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
riley 00d9e3de88 Fixed error where assignment was not within a combinational/sequential block 2026-09-08 18:23:27 +10:00
riley b926d71523 Updated seven segment test bench to reflect prior commit 2026-09-03 16:58:11 +10:00
riley 3e8aa911ce Made RSIOut the LSB to correspond with wiring configuration 2026-09-03 16:56:11 +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 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
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
