WebThe method can statistically estimate the minimum and maximum delay of all possible paths and signal transitions in the circuit, considering the practical implementation of circuits, and information about the parameters’ toler- ances. The method uses a VHDL description and is verified on ISCAS85 benchmark circuits. WebJun 14, 2024 · The checkpoint theorem is just a compressed version for equivalent and dominant fault collapsing. In the previous circuit, we have 4 primary inputs and 6 fanout branches. Hence, there are a total of 2x (4+6) = 20 stuck-at faults to test. This is a pretty good approximation we can do without applying fault collapsing. campervans for sale sunshine coast
