What MoDeCH does

MoDeCH (株式会社モーデック) is a Japanese semiconductor device modeling and design-support company founded in 2002 and headquartered in Hachioji, Tokyo. The company develops SPICE-compatible device models, proprietary X-series modeling software (X-verifier, X-tractor, X-degner, X-skew, X-aminer), the RODEM graph digitization tool, and high-frequency measurement services including a 110GHz S-parameter capability developed jointly with Kioxia. Its technical focus spans power electronics (SiC, GaN MOSFET, IGBT), RF/mm-wave devices, and high-speed digital / automotive electronics, serving customers that need accurate circuit simulation models not supplied by component vendors.

The business combines subscription-based model library access (Model On!, with multiple tiers including a 2025-launched Model On! Start Up plan), per-unit individual model sales through the Model On! Search EC site, project-based commissioned modeling and measurement services, and perpetual/annual software licenses (e.g., RODEM campaign pricing of ¥158,000 perpetual / ¥58,000 annual). Distribution is multi-channel: direct sales, own EC sites, and partnerships with Innotech Corporation (majority owner since April 2020 and primary semiconductor distributor), Zuken Inc. for LTspice-channel sales, and an MoU with Belgium-based Incize for EU-Japan market access.

MoDeCH operates across five primary segments — power electronics, RF/mm-wave, high-speed digital/automotive, semiconductor/IC design, and general electronics — and supports models for the dominant simulator ecosystems (Cadence PSpice/Spectre, Keysight ADS, LTspice, HSPICE, Eldo, Ansys Designer/Simplorer, ngspice). With 11-50 employees, the firm remains small and specialized but is structurally anchored by Innotech's distribution scale, with reported Model On! subscription retention of approximately 90% over four years.
