Gobi, Keep in mind that the primary purpose of ICT is to verify assembly, not performance. So while it is possible to test a chain of nets as a group, it is less effective for the purpose of the test. For example, test points on either end of a chain of 6 components electrically connected could tell you that one of those components has an open connection, but it would not tell you which component is open. If you were able to add test points on each connecting net, the ICT results would pin point exactly which component failed. Sometimes, space constraints require this less effective method. What you are describing is more of a functional test, to be performed after it has been determined that the assembly is correct. Functinal testing does not require testing each component, instead testing the result of the circuit.
