10.26165/JUELICH-DATA/FERGKU Menzel, Stephan(Peter Grünberg Institut (PGI-7))Bengel, Christopher(RWTH Aachen University) Jülich DATA 2025 The JART VCM v1b var model represents an extension of the JART VCM v1b model which additionally considers device-to-device and cycle-to-cycle variability. The ECD can be seen in Fig. 1. The physical equations are the same as in the v1b model. Device-to-device variability is achieved through parameter variation of specific parameters during initialization of the devices and cycle-to-cycle variability is achieved through modification of the same parameters during the simulation run.
