01 / Design
RTL & digital logic
How Verilog and SystemVerilog describe circuits—and how open tools turn that description into hardware.
The open hardware frontier
Silicon is more interesting when it’s open.
Explore the ideas, tools, and people making hardware more transparent—from RTL and RISC-V instruction sets to the physics of lithography.
