STA Handbook
10 chapters on STA concepts, delays, crosstalk and timing verification, with interview Q&A.
Static Timing Analysis Library
Static Timing Analysis (STA) Books & Guides
Three books for timing signoff: the STA Handbook for concepts, the PrimeTime Mentor Guide for Synopsys PrimeTime and the Tempus Mentor Guide for Cadence Tempus. PrimeTime and Tempus are free to read online; every book is ₹199 as an offline PDF. Some flows still call this analysis MCMM; pdVerse uses MMMC.

Deep Signoff Curriculum
Static Timing Analysis Signoff Curriculum & Methodology
Static Timing Analysis (STA) is the definitive signoff methodology for digital ASIC and SoC designs. Unlike dynamic simulation which only exercises testbench vectors, STA mathematically proves that every register-to-register, input-to-register, and register-to-output path satisfies setup, hold, recovery, removal, and minimum pulse width requirements across all PVT corners and operating modes.
