CMOS VLSI Design

MOS transistors, CMOS gates, delay, power, memory (SRAM/DRAM), datapath and design-for-test.

CTS & Concurrent Optimization

Clock tree synthesis with simultaneous clock-and-data optimization for tighter timing closure.

Clock Tree Synthesis

Complete CTS reference — concepts, prerequisites, step-by-step workflow, verification and troubleshooting.

Design Constraints (SDC)

Timing constraints — clocks, generated clocks, I/O delays, path exceptions, OCV and MCMM.

Engineering Change Orders (ECO)

ECO types, unconstrained and metal-only flows, signoff-driven ECO, spare cells and timing fixes.

Low-Power Implementation

UPF/CPF power intent, isolation cells, level shifters, retention flops and power-gating flows.

Mixed (Concurrent) Placement

Simultaneous macro and standard-cell placement with MSV awareness and incremental tuning.

Multivoltage & Low-Power Design

Power domains, supply networks, power gating, state retention, always-on logic and low-power sign-off.

Routing & Postroute Optimization

Global routing, track assignment, detail routing, DRC convergence, SI and postroute optimization.

Static Timing Analysis

STA — cell delay, interconnect, setup/hold checks, MCMM, OCV, crosstalk, IR drop and sign-off.

Timing & Power Optimization

Pre-CTS, post-CTS, post-route optimization, useful skew, SI fixes, leakage reduction and ECO closure.
