Power Integrity
Challenges
High-speed power transients imply that
PI requires broadband DC to multi-GHZ analysis
for complete steady-state, transient, aned
harmonic simulation.
Impedance profiles built from these
solutions need to be flexible, accurate, and
complete.
Reduced-cost packages and systems
imply that complex 3D effects are the norm,
necessitating large-scale high-speed 3D
simulation to capture all dominant coupling
effects.
The simulation
needs to be sufficient accurate to represent
appropriately all coupling effects in the time
domain through the generation of accurate,
error-controllable SPICE
models.

Fundamental Solutions
Needed
PI challenges necessitate
critical requirements in underlying
design-enabling field
solvers. In
particular, the Maxwell's equation solution
needs to be broadband, spanning the DC to
multi-GHz frequency range with a single,
unswitched
solver. The
solution needs to be full-wave and truly
three-dimensional, in order to create accurate
impedance profiles and electrical models while
account for complex mode-types and
edge-coupling effects.
The methodology needs to solve
large-scale problems in fast simulation times
in order to reduce design cycles and to keep
the design-cycle time short. High-dynamic range
requirements imply that speed and scale
enhancements cannot come at the cost of
accuracy.
SPICE
netlist generation needs to be automatic
and error-free and to cover all aspects
of passivity, causality, and overall
fidelity in the time-domain
solution.
