"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. " - Chisel uint to sint
