System Verilog "ref" is a nice reference instead of "value"
WebWith the parameterized declaration for Channel above where the default type for Tr is bit, we can do the following: Parameterized Extension. Note. class Chan1 # (type P=real) extends Channel; The default type for Tr is still bit and declares a type parameter for Chan1 with default type of real. class Chan2 # (type P=real) extends Channel ... In SystemVerilog, Pass by value is the default mechanism for passing arguments to subroutines. This argument passing mechanism works by copying each argument into the subroutine area. If the subroutine is automatic, then the subroutine retains a local copy of the arguments in its stack. fall creek recreation area
