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

  +
Features of CλaSH:
  +
  +
* 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.
  +
* Compile your designs for fast simulation.
  +
* Higher-order functions, in combination 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.

* Multiple clock domains, with type safe clock domain crossing.
  +
* Template language for introducing new VHDL/(System)Verilog primitives.

What is CλaSH

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

Features of CλaSH:

  • 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.
  • Compile your designs for fast simulation.
  • Higher-order functions, in combination 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.
  • Multiple clock domains, with type safe clock domain crossing.
  • Template language for introducing new VHDL/(System)Verilog primitives.

Good Boards to Bring to BayHac2017 CλaSH Hackathon

I will bring a few DE0-nano boards to the hackathon. They are quite inexpensive and can be purchased for about $85 on DigiKey https://www.digikey.com/products/en?mpart=P0082&v=771, adafruit https://www.adafruit.com/products/451 and other locations on the web.

A good list of boards can be found here: https://www.reddit.com/r/haskell/comments/5opec9/haskell_to_hardware_project_clash_701_released/
