WebThe goal of ‘Scan Insertion’ is to make a difficult-to-test sequential circuit behave (during testing process) like an easier-to-test combinational circuit. Achieving this goal involves two steps – 1. Converting Regular Flop to Scan Flop All the flops in the design are converted into scan flops (as shown in Figure 4), except – WebScan chain insertion can have a large impact on routability, wire- length and timing of the design. We present a routing-driven methodology for scan chain ordering with minimum wirelength ob- jective. A routing-based approach to scan chain ordering, while potentially more accurate, can result in TSP (Traveling Salesman ...
