ROHM Solution Simulator

ROHM Solution Simulator is a new web-based electronic circuit simulation tool that can carry out a variety of simulations, from initial development that involves component selection and individual device verification to the system-level verification stage. This makes it possible to quickly and easily implement complete circuit verification of ROHM power devices (i.e. SiC) and ICs (e.g. driver and power supply ICs), in simulation circuits under close to actual conditions, significantly reducing application development efforts.
The simulator was developed to work with the SystemVision Cloud simulation platform from Mentor, a Siemens business, a leader in electronic design automation software with an extensive track record in the automotive and industrial equipment industry. As a result, users with an SVC account can also perform verification in a more realistic environment by incorporating simulation data executed by the ROHM Solution Simulator into their own SVC workspace.
