riley c717bf189c Added comment to document the zero-flag 2026-10-16 11:57:55 +11:00
riley 5ae9125e06 Fixed a couple bugs introduced from merge-conflict resolution 2026-10-16 11:50:07 +11:00
riley 8a682347f0 Merge branch 'main' of ssh://git.rileyk.au:19482/TroubleElectrical/FPGA_Uni 2026-10-16 11:44:03 +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 92a0cb17da Updated assignment 2 to reflect prior changes. Fixed instruction ordering for register file module (again). Fixed typo that limited the space the ALU could write its flags out to. Swapped ordering to be correct when determining if we are storing the result from ALU or MEM. 
Added a QUARTUS_SYNTH around the display logic at the end of the module.
Partially fixed control_unit module, still seems to need some changes as branching doesn't appear to work at all.
