3 Marketing  What is a GPS Waypoint Navigator? –Uses & Applications  Hardware VS Software –Very low-power –Compact ~ 2 Slides By: Charles

4 Design Process  Description  Requirements  Math  High-Level Simulations  Behavioral Verilog  Structural Verilog  Schematics  Layout ~ 5 Slides By: Nan

5 Algorithm Description   Brief overview – – How it works?   Clock Breakdown – –Why so many???   System Flow – –System Inputs  Blackbox Outputs  Blackbox Inputs  SystemOutputs ~ 15 Slides By: Shanshan / Julio

6 Verification  MATLAB  Behavior Verilog  Structural Verilog  Schematics –Begin timing verification & serialization  Layout  Timing (post layout) ~ 10 Slides By: Julio

7 Floorplan Evolution  Original Floorplans –Description –Why were they modified/scrapped?  Latest Floorplan –Description –Why is it acceptable? ~ 5 Slides By: Shanshan

8 Layout  Layer Masks  Full chip layout  Full chip layout w/ overlaid floorplan ~ 8 Slides By: Nan

9 Issues & Solutions  Grouping & Re-grouping  Initial I/O count > 200  Serialization  Architecture Complexity –Trade off between I/O pins & accuracy –1 ft. Accuracy  4 Clocks –Chip Interface (i.e. unit conversions) –Blackbox or no Blackbox???  Overall Design Size –Transistor Count –Bus Sizes / Buffers –ECE File Space  Power  Simulations  Cadence ~ 3 Slides By: Charles

10 Specifcations  Pin Specs  Circuit Specs –Transistor Counts –Area –Density  Delays –Why they don’t mean anything???  Power ~ 3 Slides By: Charles

11 Conclusion By: Charles ~ 1 Slide

12 Updates  Layout 99% done as of 8:59:59am this morning  Finished analog sims for all functional blocks  Cadence limits our top-level testing capabilities
