Value Members

  1. def N(width: Int = 1): BitPat

    Creates a BitPat of all 0 of the specified bitwidth.

    Creates a BitPat of all 0 of the specified bitwidth.

    Example:

    1. val myN = BitPat.N(4)  // equivalent to BitPat("b0000")
  2. def Y(width: Int = 1): BitPat

    Creates a BitPat of all 1 of the specified bitwidth.

    Creates a BitPat of all 1 of the specified bitwidth.

    Example:

    1. val myY = BitPat.Y(4)  // equivalent to BitPat("b1111")
  3. def apply(x: UInt): BitPat

    Allows UInts to be used where a BitPat is expected, useful for when an interface is defined with BitPats but not all cases need the partial matching capability.

    Allows UInts to be used where a BitPat is expected, useful for when an interface is defined with BitPats but not all cases need the partial matching capability.

    Note

    the UInt must be a literal

  4. def apply(n: String): BitPat

    Creates a BitPat literal from a string.

    Creates a BitPat literal from a string.

    n

    the literal value as a string, in binary, prefixed with 'b'

    Note

    legal characters are '0', '1', and '?', as well as '_' and white space (which are ignored)

  5. def bitPatToUInt(x: BitPat): UInt

    Allows BitPats to be used where a UInt is expected.

    Allows BitPats to be used where a UInt is expected.

    Note

    the BitPat must not have don't care bits (will error out otherwise)

  6. def dontCare(width: Int): BitPat

    Creates a BitPat of all don't cares of the specified bitwidth.

    Creates a BitPat of all don't cares of the specified bitwidth.

    Example:

    1. val myDontCare = BitPat.dontCare(4)  // equivalent to BitPat("b????")
