The enable to the control test points can be used to turn off the test points if desired.
WebDec 21, 2016 · Description. Design for test (DFT) is also important in low-power design. To increase test coverage, ensure that the clock-gating logic inserted by the low-power engine is controllable and observable. First, select a clock-gating cell that contains test control logic, indicating whether the test control logic is located before or after the latch. cim ontologyWebSynopsys TestMAX DFT is a comprehensive, advanced design-for-test (DFT) tool that addresses the cost challenges of testing designs across a range of complexities.
