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. Webimproving routing characteristics of VLSIdesigns. Many signals in a VLSI chip can be viewed as instances of multicast communica-tion. Any signal with a fanout of more than one is, in the most gen-eral sense, an example of multicast communication within an IC. However, not all such on-chip multicast instances may benet from network coding. griffis group residential llc
