I’ve implemented multiple instructions to a RISC-V processor module and I gave instructions to find the greatest common divisor of values 98 and 56, which is 14, and it is stored at the register 16 of the processor. The problem is when i try to show it on the seven segment display of nexys4 ddr board, it only displays a bunch of 0’s. Simulation of the module works just fine, but it does not work when it comes to implementation phase sadly.
