Fundamentals of VLSI design

EE-429 / 4 credits

Teacher: Burg Andreas Peter

Language: English

Summary

The course introduces the fundamentals of digital integrated circuits and the technology aspects from a designers perspective. It focuses mostly on transistor level, but discusses also the extension to large digital semicustom designs.

Content

Introduction: 
History/milestones, methodology, technology, design objectives & principles

Digital CMOS Fundamentals (Inverter):
DC characteristics, delay, rise/fall time, noise-margins, impact of  sizing

Basic CMOS logic gates:
Constructing basic logic gates, transistor sizing, gate delay considerations

Custom digital logic:
Logical effort model, sizing of gates, inverter chains

Parasitic effects:
Routing capacitance, wire resistance, Elmore delay model

Technology considerations:
Technology scaling, impact on parasitics, variabiity

Low-power design: 
Power consumption basics (leakage, dynamic), voltage-scaling, basic low-power design principles

Memories:
Embedded SRAM (6T bit-cell, organization, peripherals), SRAM stability (noise margins)
DRAM (briefly)

Fundamentals of Semicustom design:
Design flow, design abstraction, IP components, standard-cells (layout, characterization, lib, lef)

Semicustom design flow:
Logic synthesis, place & route, clock distribution, verification
