Adam StolerMilestone 7:
March 1stComponent Layout
(Corrected)
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
