The Constructing Hardware in a Scala Embedded Language (Chisel)[1] is an open-source hardware description language (HDL) used to describe digital circuits at the register-transfer level.[2][3] Chisel is based on Scala as an embedded DSL. Chisel inherits the object-oriented and functional aspects of Scala for describing digital hardware. Using Scala as a basis allows to describe circuit generators.
Circuits described in Chisel can be converted to a description in Verilog for synthesis and simulation.
Example
A (too) simple example describing an adder circuit:
class Add extends Module {
val io = IO(new Bundle {
val a = Input(UInt(8.W))
val b = Input(UInt(8.W))
val y = Output(UInt(8.W))
})
io.y := io.a + io.b
}
Usage
Although Chisel is not yet a mainstream hardware description language, it has been explored by several companies and institutions. The most prominent usage of Chisel is an implementation of the RISC-V instruction set, the open-source Rocket chip.[4] Chisel is mentioned by DARPA as a technology to improve the efficiency of electronic design, where samller design teams do larger designs.[5] Google has used Chisel to develop a tensor processing unit for the edge.
