Overall Project Objective:Design an Air-Fuel Ratio Controller for a small

gasoline engine with low emissions and low cost

Design Manager:Steven Beigelmacher

Logos are cool!!

Status• Design Proposal (done)• Architecture (done)

• High Level C Simulation• Behavioral Verilog & Test Bench• Floorplan & Structural Verilog

• Gate Level Design (done)• Top Level Schematic Verification

• Component Layout (done)• Analog simulation of SRAM and ROM• Layout of all components

• Component Simulation (90%)• Smaller Multiplier being laid out• Everything else complete

• Still to be done• Top level layout• Top level simulation
