Production proven path-based timing and clock-tree analysis
ANSYS Path FX complements existing sign-off and physical design flows. It has the performance to evaluate all of the timing paths and clock trees in a SoC for delay and variance for even the largest designs. ANSYS Path FX has production-proven accuracy to tackle the most advanced manufacturing processes, the functionality to account for all critical contributors to delay and constraints across multiple process, voltage, temperature corners and scenarios.
ANSYS Path FX makes it practical to calculate timing with variation on a full SoC without taking any shortcuts. With a fully threaded and distributed architecture and the ability to run on thousands of CPUs, turnaround time scales inversely with the number of CPUs available.
ANSYS Path FX also includes EOS and aging simulation capabilities for leading-edge designs. EOS FX simulation is a threaded, full-block/IP solution that automates vector generation for exhaustively exploring all possible EOS failures. By utilizing static FX simulation to determine voltages on every electrical node, it identifies real EOS failures with SPICE accuracy and eliminates false positive alarms. FX aging simulation is done by taking the instance-specific static probability of a stress effect, propagating the stress throughout the design and identifying long-term stress effects. By propagating the stress condition into cells — via the computation of transistor-level stress effects — the solution can accurately simulate the aged version of the cell and provide insights into circuit delay degradation with time.
ANSYS Path FX delivers:
Complete Path-based Critical Path Timing
ANSYS Path FX can simulate thousands of paths using standard cell models or transistor-level SPICE models, providing both corner and statistical timing results.
Full Clock Tree Analysis
ANSYS Path FX automatically identifies and simulates every clock path in your design.
Ultra-low Voltage Transistor-level Simulation
ANSYS Path FX leverages the SPICE transistor models and full waveform propagation to provide the accuracy needed to get reliable results at ultra-low voltage and advanced processes. Miller-capacitance and other effects are handled correctly, with no shortcuts.
