“…Another example is the solution of linear equation systems, which is necessary to simulate models with algebraic loops. In the past, numerous high performance linear solvers for FPGAs were developed [16][17][18][19]. To enable their usage, model preprocessing should keep linear systems instead of inserting a specific solver algorithm.…”

Advances in the development of electric vehicles challenge existing test methodologies and tools. In particular, hardware-in-the-loop test rigs to verify electric motor controllers require real-time drivetrain emulation with response times in the order of one microsecond. Field-programmable gate arrays can fulfill these requirements due to their high parallelism and the possibility to realize efficient and predictable I/O interfaces. We present an integrated methodology which translates Modelica models to VHDL hardware designs. Our methodology combines well-engineered algorithms from Modelica compilation and high-level synthesis for hardware. We demonstrate its capabilities using the example of a DC motor which was synthesized and implemented on a Xilinx Virtex-5 device.
