CS 303 Logic & Digital System Design

Logic&Digital System Design • Examles of Usage • Vending Machines • Communication System • μ-Processors • Traffic controls • Elevators • Mobile Phones • Anywhere you can imagine • etc…

Types of Digital Systems • Application Specific Integrated Circuit (ASIC) • Fast, small, less power (very efficient) • Expensive (millions of $) • Not mistake tolerant

Types of Digital Systems(Cont.) • Field Programmable Gate Array (FPGA) • Not so fast, consumes more power (less efficient than ASIC) • Cheap • Mistake tolerant

ASIC-FPGA Attention: This representation of FPGA is wrong. It just demonstrates a good functional representation.

Looks of an FPGA

Looks of an FPGA-Board

How To Design ? • Full Custom • State machine • Schematic • Hardware Description Language (HDL)

Software Tools IMPLEMENTATION SYNTHESIS SIMULATION

Let’s look at an example
