Verilog Basics for Low-Level Engineers

Purpose

Give firmware and kernel engineers enough Verilog/SystemVerilog literacy to read RTL: modules, clocks/resets, combinational vs sequential logic, bus interfaces, and why hardware behavior explains driver bugs — not a replacement for HDL design courses.

When to Use

• Reference manual unclear — RTL clarifies register behavior
• Understanding CDC (clock domain crossing) bugs
• Correlating DMA/AXI transactions with driver ordering
• Reviewing SoC block diagram with hardware team

Workflow

1. Module structure
