Advantages and Value Proposition
-
Significant Leap in Design Efficiency
Automated parameter extraction and standardized modeling processes free engineers from tedious model building and convergence debugging, allowing them to focus entirely on architectural optimization.
-
What You Simulate Is What You Get (Simulate-to-Measure Fidelity)
The high-precision engine ensures that simulation waveforms truly reflect circuit behavior, mitigating the common risk of "perfect simulation, failed hardware (measured failures)." This provides a credible foundation for design decisions.
-
Reliability Frontloading (Shift Left Reliability)
Utilize stress and sensitivity analysis right at the schematic design phase to proactively identify latent risks such as oscillation, overheating, and component over-specification. This fundamentally improves product yield.
-
Cost and Cycle Control
Replacing repetitive PCB prototyping and bench testing with high-coverage simulation directly reduces material and time costs, accelerating time-to-market.
