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

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

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 Vcc Gnd I Ckt +V-+V- Z PDN Vcc Phase 1 : Phase 2: I Ckt

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.
