Sequential clock gating provides significant power savings because it not only switches off the clock going to registers but also the datapath logic in the fanout of gated registers. However, RTL synthesis tools are not capable of identifying sequential clock gating opportunities. Fortunately, recently ...
The state-maintaining logic is functionally separated from the remainder of the circuit when the remainder of the circuit is being powered up or down to avoid short-circuiting any elements. Typical state-maintaining components are sequential logic gates. Typical non-state maintaining components are ...
Combinational loop 除对综合,形式验证,布局布线,静态时序分析有影响之外,对DFT 同样有影响,此处引用一段原话: Feedbacks may cause oscillations, races or memory-like behavior in logic, which complicates the test generation process, this may cause: Long ATPG runtime Long or hanging gate-level simulations...

Combinational circuits are digital logic circuits whose instantaneous outputs depend only on the combination of their inputs. For example, a combinational circuit could be used to add any number of inputs, or to subtract them, or to perform other mathematical operations. What is an example of a...
