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.… ...

Co-Design has introduced Systemsim, a verification environment that lets you use its own Superlog system-design language (see “Get a handle on design languages” in this issue) alongside code written ...

[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 ...
