Spade: An HDL Inspired By Modern Software Languages
summary
Spade is an open source EUPL‑1.2 HDL that adds native pipelining (declare pipeline depth, use explicit r registers; compiler retimes and errors when values are used too early, example latency two), a rust-inspired type system and affine‑typed ports to prevent misuse, and a package manager/build tool swim with plugins that fetch cores and chain yosys/nextpnr to ecp5 flows. A two‑lane CSI‑2 camera parser, HDMI output and a Fomu upload path are built; camera pipeline works (monitor rotation aside) and swim can produce a blinking Fomu bitstream.
