Most (if not all) the examples are tested with Icarus Verilog. Implementing a shift register is actually one of the most common use cases of the for loop. Modules usually have named, directional ports (specified as input, output or inout) which are used to communicate with the module. It also resets the counter if the signal rstn becomes 0, making it an active-low reset. We will also write test benches for all the circuits we design. Verilog HDL is commonly used for design (RTL) and verification (Test-bench) purposes for both Field programmable gate arrays (FPGA) and Application-specific Integrated Circuits (ASIC).
