UltraSim Overview
UltraSim is a high-performance, full-chip, hierarchical circuit simulator that combines SPICEprecise
accuracy and virtually unlimited capacity for memory, digital, and mixed-signal IC
designs. UltraSim addresses critical deep submicron (DSM) analysis issues such as timing,
noise, power, IR drop, and reliability, including hot-carrier effects. It is the first commercially
available solution to successfully simulate a billion-transistor memory circuit.
How UltraSim Does It
UltraSim features Celestry's universal ODE solver engine
and proprietary adaptive-hierarchy compaction technology
to handle your largest memory or system-on-chip (SoC)
designs. Using the same simulation engine as in hierarchical
mode, UltraSim is as adept at running flat simulations as
the best circuit simulators on the market today.
Celestry's industry leading knowledge of device modeling
and device physics is the foundation for the unique
technological advantage UltraSim holds. With an available
best-in-class RC reduction engine from Celestry's widely
adopted Nautilus-RCR product, UltraSim can further
boost the capacity and performance of the post-layout
simulation by several orders of magnitude. The tight
integration to the hierarchical RC extraction makes
UltraSim the only complete full-chip transistor-level
post-layout verification solution.
UltraSim Benefits:
◆ Speeds up full-chip simulation 10x to 1,000x
User-selectable accuracy to within 1% of SPICE
◆ Virtually unlimited simulation capacity

simulation with adaptive
hierarchy-compaction
technology to achieve high
capacity
◆ Universal ODE solver engine to
achieve high performance
without sacrificing accuracy

Why UltraSim?
Until now, when you wanted simulation results with
SPICE accuracy you had to trade off circuit size,
simulation performance, or both, causing costly
design sign-off delays. With Celestry, you no longer
need to sacrifice accuracy, capacity, or performance.
This means you can enjoy benefits not available with
other tools:
◆ Virtually unlimited capacity.
◆ Ultra-accurate and Ultra-fast simulation.
◆ Hierarchical and flat circuit designs in
a single simulator
UltraSim is a fast, full-chip hierarchical simulator that
can handle billion transistor memory designs and
above, as well as multi-million transistor logic and
mixed-signal circuits. UltraSim combines SPICE
accuracy and virtually unlimited capacity at ultra-fast
speed for your SoC designs. It contains critical DSM
analysis solutions that include timing, noise, power, IR
drop and reliability improvements, and eliminates the
need to use multiple simulation and analysis tools. It
is the industry's only integrated solution offering
hierarchical extraction, RC reduction, and hierarchical
simulation for both hierarchical and flat designs.
