  4. Overview • Background • Integrated Circuit Power • Power Delivery Network • Problems • Solution • Industry Tools • Estimation Method • HSIMPlus • HSPICE • Project Preview • Conclusion

  5. Integrated Circuit Power Taken from “Micron Proposal 09” by Tim Hollis

  6. Power Delivery Network (PDN) On-Chip Power Delivery • Power Delivery Network (PDN) • Characteristic of a PDN should provide a good complex multi-stage network supplying power to all devices in a system Vdd Vss Taken from “Micron Proposal 09” by Tim Hollis

  7. Ideal and Functional PDN • Ideal and Functional PDN will: • Deliver clean power to the Integrated Circuits • Provide low impedance and low noise reference path for signals • Does not contribute excessive Electromagnetic Interference

  8. Ideal PDN vs. Non-Ideal PDN Taken from micron proposal 09” by Tim Hollis

  9. Problems • Transistors are faster but they operate at a lower voltage supply and at a higher overall chip power • To fully simulate billions of transistors on the circuits requires an extreme amount of time • Circuits need to be analyzed to ensure the circuit will operate reliably and their simulations are accurate

  10. Current Solution in Industry • Model order reduction required due to design complexity. • “Two-Phase" (or two-pass) method employed Phase 1 : Phase 2: Vcc Vcc ZPDN ICkt + V - ICkt Gnd Gnd

  11. Current Industry Tools • Apache • Totem • Chip Power Model (CPM) • Redhawk Tools • Cadence’s VoltageStorm • Synopsys’ HSIMPlus • Hynix Semiconductor

  12. HSPICE • HSPICE is the industry's "gold standard" for accurate circuit simulation and offers foundry-certified MOS device models with state-of-the-art simulation and analysis algorithms.

  13. HSIMPlus • HSIMPlus provides a complete set of analysis tools for device-level and interconnect reliability analysis • HSIMPlus has Two-phase Method applied by it’s Power Net Reliability Analysis (PWRA) tool.

  14. Approach

  15. Project Preview Output with Single Layer Package vs. Output without Package in HSIMPlus

  16. Project PreviewOutput with Single Layer Package vs Output Without Package in HSPICE

  17. Conclusion • Power delivery noise affects the performance and correctness of our circuits • Evaluated the runtime and accuracy of HSPICE vs. HSIMPlus with various configurations • Too complex a problem to simulate with accurate tools (HSPICE) • Model order reduction tools introduce some error (HSimPlus)
