PrimeTime Add-On Features

PrimeTime PX accurately analyzes full-chip power
dissipation of cell-based designs. It provides vector-free and vector-based peak power
and average power analysis. The vectors to PrimeTime PX are either RTL or gate-level
simulation results in Value Change Dump (VCD) format or Switching Activity Interchange
Format (SAIF). PrimeTime PX provides multi-VDD and power domain analysis. It also
has an integrated graphical user interface (GUI) for visual power debugging. For more
information, see the PrimeTime PX User Guide.

PrimeTime SI (signal integrity) adds crosstalk
analysis capabilities to PrimeTime static timing analyzer. PrimeTime SI calculates the
timing effects of cross-coupled capacitors between nets and includes the resulting delay
changes in the PrimeTime analysis reports. It also calculates the logic effects of crosstalk
noise and reports conditions that could lead to functional failure. For more information,
see the PrimeTime SI User Guide.

PrimeTime VX increases the accuracy of timing
analysis by considering the statistical variation and distribution of process parameters.
PrimeTime VX accurately determines the timing behavior of a circuit under varying
parameters such as channel length, threshold voltage, and interconnect wire thickness.
Given a set of variation-aware cell libraries and interconnect data, PrimeTime VX
analyzes path timing behavior under all combinations of parameter variations. For more
information, see the PrimeTime VX User Guide.
