One-Bit Adder with Sequence Generators

This is the same as a previous circuit. The difference is that instead of interactive inputs, the circuit has three sequence generators that cycle through all the values of the input truth table.

With the circuit running, select tools... logic history window... to see a graph of the input and output levels. This graph will be similar to Mano & Kime's Figure 3-7. Digital Works does not account for gate delays, so the input and output waveforms are shown aligned rather than offset. M&K shows them offset.
