Comparator weird behaviour
I've two comparators (say, CompA & CompB) in my design, whose outputs I take as interrupts by enabling the ComparatorBus interrupt. CompA is at a lower level (threshold) than CompB. Both are continuous time blocks.
I see that CompA works fine when the i/p exceeds the threshold. But it does not give an interrupt for the vice-versa. But, CompB works great for both cases. (You may see that they have different thresholds but the same input).
The red circle in the attached image indicates the absence of a transistion that has to occur when the input falls below the threshold or in other words that which executes an ISR.
Any clarification wud be greatly appreciated.
