Chisel (an acronym for Constructing Hardware in a Scala Embedded Language^[1]) is an open-source hardware description language (HDL) used to describe digital electronics and circuits at the register-transfer level.^[2]^[3]

Chisel is based on Scala as a domain-specific language (DSL). Chisel inherits the object-oriented and functional programming aspects of Scala for describing digital hardware. Using Scala as a basis allows describing circuit generators. High quality, free access documentation exists in several languages.^[4]

Circuits described in Chisel can be converted to a description in Verilog for synthesis and simulation.
