eMEGASIM Benefits

Versatile and Adaptable

From transmission and distribution networks to power converters and motors, eMEGASIM provides an all-in-one Simulink based environment for R&D and testing. Its flexible and customizable platform adapts to a wide variety of disciplines and applications. OPAL-RT’s range of hardware, software and protocol options also ensure the expansion capabilities necessary for growth and diversification.

Minimum Ramp-up

eMEGASIM runs on the RT-LAB real-time simulation platform, which is fully integrated with the easy-to-use, industry-standard Simscape Power System, formerly SimPowerSystems, interface. This ensures the briefest ramp-up time upon initial acquisition, while saving time on an on-going basis due to the platform's familiarity to many students and new employees.


Scalable from 6 to 64 processors, and using very fast 10 Gbits/s communications links, eMEGASIM can simulate models with time steps as low as 10 μs, ensuring fast and accurate results. When combined with FPGA co-processors and OPAL-RT's RT-XSG blockset, simulation time steps can be reduced to the nanoseconds range.

eMEGASIM Software Components


The fastest, most accurate solvers for eMEGASIM applications. ARTEMiS and ARTEMiS-SSN solvers and algorithms eliminate artificial delays, while using advanced decoupling techniques for added speed and efficiency.


RT-LAB is an advanced simulation control platform that includes a complete design library for all applications and industries. Use RT-LAB to edit, compile, load, execute and analyze models.


RT-EVENTS is a Simulink toolbox offering improved speed and accuracy for discrete simulation of event-based systems. It is ideal for the simulation of high frequency modulation signals used with Firing Pulse Units and converter controls. RT-EVENTS compensates for the errors introduced when events occur between samples, and supports distributed real-time simulation. 

eMEGASIM offers direct platform compatibility with ePHASORSIM and eFPGASIM, procuring maximum versatility from large power grid simulation to highly detailed power electronic simulation.
