  4. Sprinkler BuddyMarketing • Why Sprinkler Buddy ?

  5. Sprinkler Buddyat-a-glance $52 Million market potential 1.1 Billion potential customers 100%yearlymarket growth 6month payback to customer

  6. Large and Untapped Market • 95% of the 1.1 billion farmers are from developing nations • 60% of irrigation water wastage in these nations

  7. The South Asian Farmer • Average yearly income is $795.56 • 25% of yearly earnings are lost In water costs

  8. Current Solutions: Expensive/Un-automated • Prohibitively expensive for the average farmer • Customer forced to make a choice • Do not adhere to standard guidelines

  9. Sprinkler Buddy: The low cost, automated solution !

  10. Minimal Setup and Service Solar Powered Design UN Certified Water Output Calculations Low Cost Alternative The Sprinkler Buddy Advantage

  12. BehavioralDescription • Detailed description of each mode using flowcharts • Translation of algorithm to hardware • FSM specifications • Sharing of FPUs • Interaction between modes • Detailed description of main FSM (power)

  13. DesignProcess • Verilog • Verification and simulation of FSM control • Floor Plan • Describe placement method • Schematic • Optimal Sizing • Selection of logic style according to power requirements • Power shut off integration • Layout • Compact custom shaped designs • FSMs • Power and Clock Distributions

  14. Floor PlanEvolution • Show all iterations • Describe reasoning behind differences • Display all 7 versions

  15. Layout • Show cool layouts • All major components • Power Gating • FSMs • Show different metal layers

  16. Verification • Verification methodology • Outputs from all modes • VDD gating simulation

  17. VDD Rise Verification
