eHS FPGA-based Electrical Solver.

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

It provides a drag-and-drop interface that automatically generates an electric circuit model for the eFPGASIM platform from non-real-time models created in tools such as SimScape Power Systems (SPS), PSIM, PLECS Blockset or Multisim, without having to program the FPGA, thus obviating the need for FPGA or VHDL programming expertise.

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


Higher resolution simulations for power electronics in 3 simple steps

Once models are imported and converted, the eHS Solver automatically programs the simulator chassis' FPGA to address higher resolution simulations in the 2ns - 2us time-step range, without users needing any FPGA or VHDL programming expertise.

eHS then 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 eHS Solver is available in a number of variants optimised for the FPGAs in different simulator chassis.
