ORTiS solver codegen: C++ code generation tools for high performance, FPGA-based, real-time simulation of power electronic systems

Abstract

The solver code generation tools of the Open Real-Time Simulation (ORTiS) framework are a C++ library and CLI tool designed to create real-time simulation solvers for power electronics systems. These C++ defined solvers – generated by the tools – support high level synthesis to HDL, enabling the implementation of FPGA solvers capable of nanosecond resolution in real-time. The ORTiS Solver Codegen tools support the creation of multi-FPGA solvers and the use of user-defined power electronic component models; system level models are described by netlists. These tools enable engineers to perform hardware-in-the-loop testing of power electronic systems with high frequency dynamics, using time steps as small as 35 nanoseconds.
