WebAs of Chisel v3.4.3 (1 July 2024), the width of the values is always inferred. To work around this, you can add an extra Value that forces the width that is desired. This is shown in the example below, where we add a field ukn to force the width to be 3 bits wide: WebJul 16, 2024 · A hardware design described in Chisel is quite literally a Scala program that, when executed, generates a hardware graph composed of Chisel Nodes that is then passed to a back-end which generates a cycle-exact replica in either C++ or Verilog (or whatever other formats supported by the backend). pooh butterflyWebChisel/FIRRTL: Width Inference Width Inference Chisel provides bit width inference to reduce design effort.

You should probably be using Chisel 3 semantics which means you should be writing. val a = Input (UInt (16.W)) The quick answer is you can get the width like: val theWidth = if (io.in0.widthKnown) io.in0.getWidth else -1. or using match.
