Package Flags

Use the -f option with cabal commands to enable flags

    dynamic (off by default)

    Build Clash binaries with GHC flag `-dynamic`. This flag should only be used for packaging purposes. Installations using cabal should use `--enable-executable-dynamic`!

    use-ghc-paths (off by default)

    Locate the GHC core libraries using the `ghc-paths` package. Note: this flag may make binaries less relocatable, by hard-coding an absolute path to the core libraries.

    workaround-ghc-mmap-crash (off by default)

    Only use this flag when hit by GHC bug #19421. See clash-compiler PR #2444.

Clash - A functional hardware description language

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 (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.
