Abstract
According to an embodiment, a test system for serially testing of finite state machine circuits using scan chains is proposed. Each scan chain is coupled to a finite state machine circuit to test the finite state machine circuit coupled thereto. Each scan chain has a number of input terminals and one output terminal. The test system includes a dispatcher input interface with a number of input terminals and multiple sets of output terminals, where each set of output terminals includes multiple output terminals coupled to the input terminals of an associated scan chain. The test system further includes a dispatcher output interface with multiple input terminals and one output terminal. The output terminal of each scan chain is coupled to one of the input terminals of the dispatcher output interface.
