  1. Kavita Arora (M3-1) Lisa Gentry (M3-2) Steven Wasik (M3-3) Karolina Werner (M3-4) Stage : 9 Mar 29 Chip Level Simulation Design Manager: Steven Beigelmacher Overall Project Objective: To design a chip for a SCUBA diver that does real-time calculations to warn the diver of safety concerns including decompressions sickness and lung overexpansion.

  2. Status • Schematic Verification (done) • LVS • PressureCalc(done) • timetoflight (done) • timeleft (done) • ascensionWatch (done) • getK (done) • safetyWatch (done) • maxDepth (done) • bottomTime (done) • Top (done) • Spice Entire Chip (in progress) M3: ProDiver 525

  3. Spice Simulation Strategy • Running an example test vector through top level design in order to get timing characteristics • In order to do this in a time efficient manner disconnecting the input to the registers in PressureCalc and adding input pins so that the pressure can be made large artificially quickly. M3: ProDiver 525

  4. TimeLeft M3: ProDiver 525

  5. AscensionWatch M3: ProDiver 525

  6. TimetoFlight M3: ProDiver 525

  7. Power Consumption • Strategy to test power consumption – test the effects of several different power levels on the module in order to find the lowest at which it still works. • Also, we want to see if making any optimizations to the layout to decrease power consumption M3: ProDiver 525

  8. Questions? M3: ProDiver 525
