Dft clock gating
http://bear.ces.cwru.edu/eecs_318/dft_asic_guidelines_atmel.pdf WebOct 26, 2024 · Clock gating is a way reducing dynamic Power dissipation by temporary turning-off clock of the Flops on certain parts of the logic or by turning-off enable on gated Flops. In other words, Flops are turned-on only if there is valid information to be stored or transferred. The accuracy with which these clocks are Turned-off is captured by clock ...

WebSep 16, 2004 · This is achieved by forcing clock-gating logic into an enabled state. Inserting any extra test control signals into the clock-gating logic will prohibit the ATPG tool from fully testing the clock control logic in the functional path. DFT is, therefore, required to improve test coverage, as shown in Figure 2.
