clash-prelude: CAES Language for Synchronous Hardware - Prelude library

This is a package candidate release! Here you can preview how this package release will appear once published to the main package index (which can be accomplished via the 'maintain' link below). Please note that once a package has been published to the main package index it cannot be undone! Please consult the package uploading documentation for more information.

[maintain] [Publish]

Warnings:

'ghc-options: -O2' is rarely needed. Check that it is giving a real benefit and not just imposing longer compile times on your users.
Packages relying on Cabal 1.12 or later should specify a specific version of the Cabal spec of the form 'cabal-version: x.y'. Use 'cabal-version: 1.18'.

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.

Flags

Manual Flags

Name	Description	Default
super-strict	Use `deepseqX` (instead of `seqX`) in register-like constructs. This can help to eliminate space leaks when using lazy data structures in registers-like constructs. This potentially slows down Clash hardware simulation.	Disabled
multiple-hidden	Allow multiple hidden clocks, resets, and enables to be used. This is an experimental feature, possibly triggering confusing error messages. By default, it is enabled on development versions of Clash and disabled on releases.	Disabled
doctests	You can disable testing with doctests using `-f-doctests`.	Enabled
unittests	You can disable testing with unittests using `-f-unittests`.	Enabled
benchmarks	You can disable testing with benchmarks using `-f-benchmarks`.	Enabled

Use -f <flag> to enable a flag, or -f -<flag> to disable that flag. More info
