You don’t usually think of simulating Verilog code — usually for an FPGA — as a visual process. You write a test script colloquially known as a test bench and run your simulation.… ...

During the implementation, the Verilog code has been written for all the internal registers of the priority interrupt controller so, that it can accomplish its task of prioritizing the various ...

[Clifford]’s main focus in Yosys is on formal verification — making sure that the FPGA will behave as intended in the Verilog code. A fully open-source toolchain makes working on this task ...
