WebThe Chisel type of a Data is a Scala object. It captures all the fields actually present, by names, and their types including widths. For example, MyBundle (3) creates a Chisel Type with fields foo: UInt (3.W), bar: UInt (3.W)). Hardware is Data that is “bound” to synthesizable hardware. For example false.B or Reg (Bool ()) . WebFeb 5, 2024 · Chisel is a Scala DSL, so the Chisel Compiler is written in Scala. Chisel Compiler generates an intermediate language called FIR (Flexible Interpretation Representation). FIR has nothing to do with Scala’s syntax FIR is converted to Verilog using a converter called FIRRTL openbps github

WebThe way to compare two chisel values is a little different than Scala, since it’s creating a circuit and not doing a comparison.
