The multirate half line model is employed to decouple two discretized systems using an inductor. The equations are similar to a PI-line section. In this example model, the goal is to use half lines to decouple the model into 2 sections one implemented on FPGA/eHS and the other one implemented on CPU/HYPERSIM. The half line is transmission line for which the user can select the total inductance and resistancecapacitance. Used with transformers, the half line can often substitute for the secondary leakage inductance and provide a decoupling delay in the global systems of equations. In real-time applications, this enables the parallelization of the computations on different CPU cores. Even in a single core or in offline simulation, the half line can increase simulation performance because it creates a delay between state-space systems on each side of it.
