sealed abstract class Printable extends AnyRef
Superclass of things that can be printed in the resulting circuit
Usually created using the custom string interpolator p"..."
. Printable string interpolation is
similar to String
interpolation in Scala For example:
printf(p"The value of wire = $wire\n")
This is equivalent to writing:
printf(p"The value of wire = %d\n", wire)
All Chisel data types have a method .toPrintable
that gives a default pretty print that can be
accessed via p"..."
. This works even for aggregate types, for example:
val myVec = VecInit(5.U, 10.U, 13.U) printf(p"myVec = $myVec\n") // myVec = Vec(5, 10, 13) val myBundle = Wire(new Bundle { val foo = UInt() val bar = UInt() }) myBundle.foo := 3.U myBundle.bar := 11.U printf(p"myBundle = $myBundle\n") // myBundle = Bundle(a -> 3, b -> 11)
Users can override the default behavior of .toPrintable
in custom Bundle and Record
types.
