WebUInt (32.W): an unsigned integer that is 32 bits wide. UInt (): an unsigned integer with the width inferred. (You may get an error saying it can’t infer the width.) 77.U: to convert from a Scala integer to a Chisel unsigned int, use .U. (You may get type incompatible errors if you don’t do this correctly.) WebSInt, UInt, Bool Examples: val a = 5.S // signed decimal 4-bit lit from Scala Int ... .W is used to cast a Scala Int to a Chisel Width.
