Kodsnack

Fredrik chats with Wilson Snyder about Verilator, chip design, performance, and open hardware. This episode is a bit of a follow-up to episode 389 where Robert Wikandertalked - in Swedish - about verification of circuit designs. Afterward, Robert mentioned that we should really ask Wilson Snyder to talk about Verilator, and here we are! Wilson works with CPU and other hardware design, and is one of the lead developers of Verilator. When you design hardware, hardware description languages come in handy - you use them to describe hardware precisely. Then you can generate runnable code simulating the hardware, and run batteries of tests against it without needing to manufacture physical hardware. Verilator is one tool for turning code in the Verilog hardware description language into C++ or Systemc. The major competing tools are more on the interpreter side - which means that Verilator usually has a performance advantage. Oh, and it’s GPL licensed as well. As we discuss, Verilator doesn’t actually support all of
