➀ Min Pulse Width (MPW) checks are critical for preventing logic errors and metastability in sub-5nm designs, requiring robust Static Timing Analysis (STA) that accounts for waveform degradation, crosstalk, and process variations.

➁ Duty cycle degradation in clock networks, influenced by RC filtering, asymmetric rise/fall delays, and PVT effects, must be mitigated through precise clock tree synthesis and jitter modeling during timing signoff.

➂ Proactive strategies to fix MPW violations include optimizing clock network integrity, adjusting PLL placement, and implementing early MPW checks during the synthesis phase to avoid costly silicon re-spins.
