Reducing the bill of materials of my Hardware Watchdog timer

One nuance of the first few iterations of any new design is that rarely comes optimized in every important aspect from scratch.

It is very difficult to cover everything, when we are creating something new from the ground up. The creation process is by itself a very good sink of our cognitive energy and focus, leaving little room for a more pedantic mode of thought.

It was proven by Alan Turing back in 1936 that the halting problem applies for computing in general, and our contemporary computing machines are no exception.

Would predicting the crashing of an algorithm or program be a possible function, and we would be able to know the edge cases that cause an application to fail or enter a loop, without having to explore the actual scenarios to find these edge cases. To put it simply we would only have to ask the algorithm in which conditions it would enter a loop or end unexpectedly, and by not providing these inputs we would with absolute certainty not enter these scenarios.
