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/
