Clash: a functional hardware description language - Prelude 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:

• Prelude library containing datatypes and functions for circuit design

To use the library:

• Import Clash.Prelude
• Alternatively, if you want to explicitly route clock and reset ports, for more straightforward multi-clock designs, you can import the Clash.Explicit.Prelude module. Note that you should not import Clash.Prelude and Clash.Explicit.Prelude at the same time as they have overlapping definitions.

A preliminary version of a tutorial can be found in Clash.Tutorial, for a general overview of the library you should however check out Clash.Prelude. Some circuit examples can be found in Clash.Examples.

The constructor, (:-), is not synthesizable.
