Python nand Examples

Example #1

    sim = logsim.Sim()
    for values in truth_table(in_wires):
        for wire, value in zip(in_wires, values):

        sim.ticktock()
        print ' '.join(map(str,
                           wire_values(in_wires) + wire_values(out_wires)))


def wire_values(wires):
    return tuple(wire.value for wire in wires)


def truth_table(wires):
    return product(*[(0, 1)] * len(wires))


if __name__ == '__main__':
    a = logsim.Wire()
    b = logsim.Wire()
    tabulate([a, b], [logsim.nand(a, b)])
    print ''
    tabulate([a, b], [a & b])
    print ''
    tabulate([a, b], [a | b])
    print ''
    tabulate([a, b], [a ^ b])
