PSIM’s SPICE Module, powered by CoolCAD Electronics’ CoolSPICE engine, provides the capability to run SPICE simulation in the PSIM environment.
PSIM, an industry standard for system-level and control simulation, is excellent for simulations which require a longer simulation time to understand their full impacts. SPICE excels in device simulation, which allows for the study of things like parasitic interactions and gate drive with short simulations. With a vast library of SPICE models for industrial devices, SPICE provides the ability to analyze a particular device in detail, for example, the turn-on and turn-off transient of a semiconductor device.
We anticipate that users will use PSIM to study:
- Topology verification
- Control loop and stability
- Steady state junction temperatures and other thermal simulations
- Component sizing such as energy storage devices
- Code generation
Once the designer has an understanding of their converter it is then appropriate to dive down to a device level simulation by swapping ideal switches for SPICE models. Swapping to SPICE models will allow the designer to study:
- Gate drive requirements
- Switching and conduction losses
- Parasitic interactions
- Switch transition stresses
Currently there is no single simulation solution that provides the speed of system level simulations with the option to quickly and efficiently switch to a device level SPICE simulation. The integration of a SPICE engine into PSIM allows for users to greatly reduce development time as a simulation does not need to be re-made in a new environment to study device level interactions. With one schematic for both device simulations and system level simulations it is easy to iterate the design without worrying about version control issues.
The combination of PSIM and SPICE provides the ultimate environment for all your design needs.
To define the SPICE model statement, use the SPICE Directive block. This block can be found under the PSIM menu, in Element > SPICE > SPICE Directive Block.
In this block, one can enter any SPICE directives which are not found in the PSIM menu. All the content in this block will be inserted in SPICE netlist for simulation and for netlist generation.
You also can define SPICE models through a library file.

With the PSIM engine and SPICE engine in one integrated environment, users will be able to switch easily between running PSIM simulation and SPICE simulation.
Such a combination gives users the capability to have the proof of concept quickly in PSIM, and then zoom in to study a circuit in detail in SPICE.
Functions are provided such that SPICE netlists from other SPICE software can be easily imported and simulated in PSIM.
