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

Features of CλaSH:

  * Strongly typed, yet 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
    `Signal`s, lead to natural descriptions of feedback loops.

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