XNOR

So, the following combinations are valid combinations for the state analyzer, if timers are on:

(a+b) ∙ (In_Range2 + Timer2 > 400 ns)

(c ∙ Out_Range1) + (f xor g)

The following combinations are not valid, because resources cross pair boundaries:

(a + c)

(d + Timer1 < 400 ns)

The first example shows that a and c cannot be combined at the first level. You can get around this, however, by combining them at the second level.
