ClockDivider2

class ClockDivider2 extends ScalaBlackBox

This black-boxes a Clock Divider by 2. The output clock is phase-aligned to the input clock. If you use this in synthesis, make sure your sdc declares that you want it to do the same.

Because Chisel does not support blocking assignments, it is impossible to create a deterministic divided clock.

    getOutput is called to determine the value for the named output at the current state of the system. The proper way to do this is to not use the inputValues. Instead useinputChanged to supply a black box with its inputs.

    inputValues

    This is a list of BigInt values that are in the same order as the outputDependencies lists them

    tpe

    The concrete type of this output
