WebSep 19, 2016 · If you are only doing static indexing (based off scala.Int, etc.) then using scala collections (like Vector, List, etc.) would work fine. Otherwise, if you need dynamic indexing you have to use a Vec and, since this dynamic indexing is effectively muxing, you need to have everything be sized homogeneously. higgins painting perth

"WebApr 4, 2024 · In Chisel, a raw collection of bits is represented by the Bits type. Signed and unsigned integers are considered subsets of fixed-point numbers and are represented by types SInt and UInt respectively. Signed fixed-point numbers, including integers, are represented using two's-complement format. Boolean values are represented as type Bool. " - Chisel uint to sint
