object EspressoMinimizer extends Minimizer with LazyLogging

A Minimizer implementation to use espresso to minimize the TruthTable.

espresso uses heuristic algorithm providing a sub-optimized) result. For implementation details, please refer to: https://www.springerprofessional.de/en/logic-minimization-algorithms-for-vlsi-synthesis/13780088

a espresso executable should be downloaded from https://github.com/chipsalliance/espresso

If user want to user the this Minimizer, a espresso executable should be added to system PATH environment.

  14. def minimize(table: TruthTable): TruthTable

    Minimize a multi-input multi-output logic function given by the truth table table, with function output values on unspecified inputs treated as default, and return a minimized PLA-like representation of the function.

    Minimize a multi-input multi-output logic function given by the truth table table, with function output values on unspecified inputs treated as default, and return a minimized PLA-like representation of the function.

    Each bit of table[]._1 encodes one 1-bit input variable of the logic function, and each bit of default and table[]._2 represents one 1-bit output value of the function.

    table

    Truth table, can have don't cares in both inputs and outputs, specified as [(inputs, outputs), ...]

    returns

    Minimized truth table, [(inputs, outputs), ...]
