How a 25 MHz Clock Becomes 307,200 Pixels on a Screen

A deep dive into the `simple_480p` VGA timing generator, revealing how two counters and a handful of comparators produce the exact sequence of signals required to drive a 640×480 display at 60 Hz — all from first principles in Verilog.

One Processor, Two Worlds: Running FPGA Hardware on a Desktop Without Changing a Line of RTL

A detailed walkthrough of the `sim_top` module in this Wordle project — a Verilator-based simulation harness that virtualizes keyboard input and VGA output, allowing the same MIPS processor design to run interactively on a desktop computer without modification.
