Tutorial: Basic VLSI Design (Douglas A. Pucknell) — Practical Guide This tutorial distills actionable concepts and workflows from the textbook "Basic VLSI Design" by Douglas A. Pucknell into a compact hands-on guide you can use to design, simulate, and layout simple CMOS VLSI circuits. Assumes basic digital electronics knowledge, access to a CMOS SPICE (e.g., ngspice/BSIM), a logic simulator, and a layout tool (e.g., KLayout, Magic, or commercial tools). 1. Core concepts (quick reference)

CMOS logic uses complementary NMOS (pull-down) and PMOS (pull-up) networks; static CMOS yields rail-to-rail outputs and low static power. MOS transistor operation regions: cutoff, triode (linear), saturation — choose models for switching and sizing. Static electrical parameters: Vt (threshold), Cox, µn/µp, W/L ratio — determine drive and delay. Logical effort estimates stage sizing and delay using g (logical effort), h (electrical effort), and parasitic delay p. Layout rules: minimum width/spacing, well/tap placement, diffusion and poly connectivity, metal routing, contacts/vias. Parasitics: interconnect resistance and capacitance dominate at advanced geometries; must be modeled for timing and power.

Specification

Define function, timing (clock period), load capacitance, supply (Vdd), technology node.

Circuit design (schematic)

Convert boolean function to CMOS static logic (pull-up = dual of pull-down). Use sizing rules: start with minimum W/L for non-critical devices; size critical path devices via logical effort or RC models.

Simulation (functional + timing)

Run DC and transient SPICE simulations with realistic input ramps to verify logic levels and switching. Extract propagation delay (tPLH/tPHL), rise/fall times, static currents. Check noise margins. "Basic VLSI Design" by Douglas A

Layout (physical)

Implement single-cell layout obeying design rules: ensure correct diffusion, poly gates, contacts, and wells. Place well/tap/power rails; route signals with minimum metal layers first, reserve higher metals for long wires.
