Every Tool You Need. Nothing You Don’t.
A complete simulation environment purpose-built for power electronics — from sub-microsecond transient analysis to full thermal validation.
Solver Technology
Event-Driven Solver
DSIM computes only at switching transitions using a discrete-state, event-driven approach — delivering results in seconds, not hours.
Physical Switch Models
Real semiconductor behavior for SiC MOSFETs, GaN HEMTs, Si IGBTs, and diodes — including switching transients, conduction losses, and parasitic effects.
Robust Convergence
No convergence failures, even with hundreds of active switches. DSIM’s solver is designed for solver stability across complex topologies.
AC Sweep Analysis
Superfast AC sweep for switch-mode circuits. Analyze frequency response and loop gain across operating points without manual setups.
Thermal Simulation
Electro-Thermal Coupling
Simultaneous electrical and thermal simulation with bidirectional coupling. See junction temperatures evolve alongside electrical waveforms.
Manufacturer Loss Data
Import thermal impedance networks and loss lookup tables from device datasheets for validated thermal models.
Thermal Network Editor
Build Foster and Cauer thermal networks graphically. Model heatsinks, TIMs, cold plates, and ambient conditions.
Analysis & Visualization
Waveform Viewer
High-resolution oscilloscope-style waveform display with cursors, measurements, FFT, and multi-channel overlay.
Parametric Sweeps
Sweep any parameter (frequency, duty cycle, load, temperature) across thousands of combinations with automatic result collection.
Efficiency Maps
Generate full efficiency maps across operating conditions. Identify optimal design points automatically.
Scripting & Integration
Python API
Full simulation control from Python. Automate simulation runs, post-process results, and integrate into CI/CD pipelines.
Custom C Blocks
Embed custom C code for control algorithms, digital controllers, and behavioral models. Compiled for maximum speed.
FMI / Co-Simulation
Import and export Functional Mock-up Units (FMUs) for multi-domain co-simulation with mechanical, thermal, and control models.
