The scan chains are used by external automatic test equipment (ATE) to deliver test pattern data from its memory into the device. These paths are specified to the ATPG tool for creating the path delay test patterns. Since scan test modifies flip flops that are already in the design to enable them to also act as scan cells, the impact of the test circuitry is relatively small, typically adding about only 1-5% to the total gate count. %PDF-1.4 How test clock is controlled by OCC.

Analog integrated circuits are integrated circuits that make a representation of continuous signals in electrical form. By performing current measurements at each of these static states, the presence of defects that draw excess current can be detected. Power optimization techniques for physical implementation. There are very few timing related defects at these larger design nodes since manufacturing process variations cause relatively small parametric changes that would affect the design timing.
