Learning Verilog For FPGAs: Flip Flops

Last time I talked about how to create an adder in Verilog with an eye to putting it into a Lattice iCEstick board. The adder is a combinatorial circuit and didn’t use a clock. This time, we’ll finish ...

Simulating The Learn-by-Fixing CPU

Last time I looked at a simple 16-bit RISC processor aimed at students. It needed a little help on documentation and had a missing file, but I managed to get it to simulate using a free online tool ...
