libghc-clash-lib-dev 1.6.4-1 (riscv64 binary) in ubuntu lunar

 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
 @Signal@s, lead to natural descriptions of feedback loops.
 .
  * Support for multiple clock domains, with type safe clock domain crossing.
 .
 This package provides:
 .
  * The CoreHW internal language: SystemF + Letrec + Case-decomposition
 .
  * The normalisation process that brings CoreHW in a normal form that can be
 converted to a netlist
 .
  * Blackbox/Primitive Handling
 .
 Front-ends (for: parsing, typecheck, etc.) are provided by separate packages:
 .
  * <https://hackage.haskell.org/package/clash-ghc GHC/Haskell Frontend>
 .
  * <https://github.com/christiaanb/Idris-dev Idris Frontend>
 .
 Prelude library: <https://hackage.haskell.org/package/clash-prelude>
 .
 This package provides a library for the Haskell programming language.
 See http://www.haskell.org/ for more information on Haskell.
