How multi-bit flip-flops save clock power, which flops can be banked, the timing and useful-skew trade-offs, and a practical method for debanking, with worked examples.

Learn clock gating in VLSI: dynamic power savings, why AND-gate gating glitches, how the integrated clock gating (ICG) cell works, clock gating checks with examples and interview questions.

What is a Clock? A clock signal is like the heartbeat of a digital system. It pulses at regular intervals, switching between high and low states with steady rise and fall transitions. In an ideal case, the clock has a 50% duty cycle, meaning the time spent high and low is equal. This rhythm is […]

What is Signal Integrity and Crosstalk? Let’s take one example. I am doing work from home in my study room attending meeting and my family is sitting in the TV room and watching some news. Even though I am sitting far, I can still hear the TV sound which is an extra unnecessary element for […]

Integrated Clock Gating (ICG) Cell & Related Concepts We always have target to close the design by meeting the PPA (Power, Performance, Area). Clock consumes most of the power as it has high switching activities. Being specific, clock consumes almost 20% to 40% of dynamic power. Even in the entire clock tree, 80% of the […]

Why clock duty cycle distorts through the clock tree, how STA computes minimum pulse width slack (worked example), how to read the report, and a step-by-step fix method, with interview questions.
