2. Status • Specification definition (done) • Architecture • Matlab Simulation (done) • Verilog Simulation (done) • Hardware diagrams (done) • Verification of Verilog - Gate Level (done) • Floorplanning (done) • Gate level design – schematic (done) • Gate Level Verification (done) • Layout • Components • basic components (DRC & LVS done) • Functional blocks (90% done) • Component Simulation (need to be done) • Spice Simulation of overall design (needs to be done) M3: ProDiver 525

3. Design Decisions • Wiring Conventions were modified • Metal 1 is used for all basic gates • Metal 2 used horizontally • Metal 3 used vertically • Metal 4 used for global routing (clk and rst) • Decided to go with a Line Decoder, transistor count changed from 1043 to 303 • Minor design changes for each functional block M3: ProDiver 525
