Integrated circuit with configurable scan path

摘要

The integrated circuit includes number of flip flops (FF1-1-FF1-m,FF-2-1-FF-2-n,FF-3-1-FF3-o) which can be connected in series upon instigation of the integrated circuit, such that the flip flops do not connect in series during the normal operation of the integrated circuit. Independent claims are also included for the following: (a) a synchronous digital circuit; and (b) a program controlled unit.
