Key Features of ROHM Solution Simulator
-
A broad library of high power circuits allows users to quickly check power device characteristics, eliminating the need for topology circuit design.
Multiple PFC, inverter, and DC/DC circuit topologies are offered that incorporate power devices such as SiC. These power devices can be changed and simulated, making it easy to compare characteristics. In addition, a gate drive circuit is included that enables simulation in an environment close to that of a real system.
-
Easily design peripheral component constants for switching regulators, linear regulators, and LED drivers
A simulation of the application circuit listed in the datasheet is provided, allowing users to simulate the startup waveforms and phase characteristics with a single click. Of course, it is also possible to perform simulation by changing the peripheral component constants and input/output conditions based on customer requirements.
-
Free and easy to use
Simply register with My ROHM to perform free web-based simulations without the need to install troublesome software. In addition, pre-configured circuits make it possible to immediately run simulations.
-
Easily add components and change circuits
Developed based on the SystemVision® Cloud(SVC) simulation platform from Mentor Graphics, a leader in electronic design automation software with an extensive track record in the automotive industry, users can freely change circuits and add components by simply copying the circuit to SVC.

Simulation Circuit
【EVK Simulation】
NEWDouble Pulse Test
We have released the double-pulse test simulation environment with the evk simulation model.
The simulation circuit includes EVK's pattern parasitic inductor and can simulate the operating waveforms of 4G-SiC MOSFETs with high accuracy. Simulation conditions such as operating voltage, gate drive circuit, and snubber circuit constants can also be changed. It can be used to reduce man-hours during evaluation of actual devices and for verification before board prototyping.
