eHS FPGA-based Electrical Solver.

eHS - or 'electrical Hardware Simulation' - is a re-programmable FPGA-based electrical solver at the heart of OPAL-RT's eFPGASIM platform.

In provides a simple and intuitive interface for automatically generating an electric circuit model for the eFPGASIM platform directly from a model created in tools such as SimScape Power System Simulink toolbox, PSIM, PLECS Blockset or Multisim, into the eFPGASIM environment, without having to reprogram the FPGA and without needing to have any FPGA or VHDL programming expertise.

It also provides off-line simulations with eHS nodal solver within Simulink.


From Modelling to FPGA in 3 Steps

eHS lets you run test sequences and make on-the-fly changes to simulation parameters quickly and easily by using the 'Test Scenario' feature.
eHS allows test engineers to jump from one set of component values to the next without stopping a simulation.



The Perfect eHS Series Tailored to Your Needs

Simply select the required number of states, switches and I/O channels from the choice of four eHS solver options: eHSx16, eHSx32, eHSx64 or eHSx128. You can read more in the eHS specifications below.
