Verilog simulation is the unglamorous but essential step between writing HDL and actually loading a bitstream onto silicon. Skip it, and you'll spend hours re-synthesizing designs to chase bugs that a five-second testbench would have caught. This tutorial from Emilio Martinez III focuses squarely on that workflow: how testbenches are structured, how you drive inputs into a device-under-test, and how you observe outputs as waveforms or console prints.

What makes this worth the time over the many other "intro to Verilog" videos is the emphasis on simulation as a first-class design activity. Beginners often treat the testbench as an afterthought — a throwaway file to prove the code compiles. But experienced FPGA engineers spend the majority of their time in simulation, not on hardware, because the debug loop is orders of magnitude faster and you can inspect every internal signal.

Expect coverage of the basic testbench skeleton (module with no ports, initial blocks, clock generation), stimulus patterns, and reading waveform output. If Martinez walks through $monitor, $display, and $dumpvars for VCD generation, you'll come away with the toolkit needed to verify any small combinational or sequential design before ever touching a dev board.

Good foundational content from a small channel that clearly wants to teach rather than chase views.
