- * Exclusive-or gate: true if either a is true and b is false, or
- * a is false and b is true; false otherwise.
- * QUESTION: how can the simulator execute this program properly without
- * HDL implementations of the underlying Not, And, and Or chip-parts?
- * Answer: since the demo folder contains no Not.hdl, And.hdl and Or.hdl
- * files, the simulator reverts to using their built-in implementations.
