  2. Status • Finished • Project Chosen • C simulations • Behavioral Verilog • Structural Verilog • Revised Floor Plan • Schematics • Pathmill Simulation of Top Level • In Progress • Layout • Layout Simulations • To Do • More Layout • Layout Simulations

  3. Transistor Counts

  4. Power Consumption

  5. Sub_16

  6. Sub_16 Simulation X = 32 Y = 7 OUT = 25

  7. Top Simulation S1 = (4 * 4 - 2) mod 127 = 14

  8. Top Simulation S2 = (14 * 14 - 2) mod 127 = 67

  9. Pathmill Results • Shift_Left = .610 ns • Shift_Right = .610 ns • Mod_P = .610 ns • Mod_Add = 8.993 ns • Partial_Products = 5.135 ns • Longest Path from Top Simulation = 12.703ns

  10. Block Area Estimates (Updated)

  11. Updated Floorplan

  12. What’s Next • Continue Layout • Simulate Layout • Power Estimations for Layout
