Clash: a functional hardware description language - As a library

Clash is a functional hardware description language that borrows both its syntax and semantics from the functional programming language Haskell. The Clash compiler transforms these high-level descriptions to low-level synthesizable VHDL, Verilog, or SystemVerilog.

Features of Clash:

  • Strongly typed, but with a very high degree of type inference, enabling both safe and fast prototyping using concise descriptions.

  • Interactive REPL: load your designs in an interpreter and easily test all your component without needing to setup a test bench.

  • Higher-order functions, with type inference, result in designs that are fully parametric by default.

  • Synchronous sequential circuit design based on streams of values, called Signals, lead to natural descriptions of feedback loops.

  • Support for multiple clock domains, with type safe clock domain crossing.

This package provides:

  • The CoreHW internal language: SystemF + Letrec + Case-decomposition

  • The normalisation process that brings CoreHW in a normal form that can be converted to a netlist

  • Blackbox/Primitive Handling

Front-ends (for: parsing, typecheck, etc.) are provided by separate packages:
