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

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

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
Current Solution in Industry
► Model
order reduction required due to design
complexity.
►

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

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)
