「ROHM Solution Simulator」は、ロームの公式Web サイト上で動作する電子回路シミュレーションツールです。部品選定やデバイス単体検証などの開発初期段階からシステムレベルの検証段階まで、幅広くWeb 上でシミュレーションできます。ロームが提供するSiC デバイスなどのパワーデバイス製品と、駆動IC・電源IC などのIC 製品を、実環境に近いソリューション回路ですばやく簡単に一括検証することが可能なため、アプリケーション開発の大幅な工数削減に貢献します。
また、本シミュレータは、電子設計自動化ソフトウェア業界大手で、自動車業界に広く実績を持つメンター・グラフィックス社製シミュレーションプラットフォーム「SystemVision® Cloud （SVC）」を採用して開発しています。このため、SVC アカウントを持っているユーザーは、「ROHM Solution Simulator」で実行したシミュレーションデータを自身のSVC 環境（ワークスペース）に組み込むことで、より実使用に近い環境で検証することも可能です。
