clash-verilog - Verilog backend for the CλaSH compiler

  • See the LICENSE file for license and copyright details

CλaSH - A functional hardware description language

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 (like VHDL), yet with a very high degree of type inference, enabling both safe and fast prototying using consise descriptions (like Verilog).

  • 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.
