Half stubline
Description
The stubline model is used to decouple two discretized system using an inductor. The equations are similar to a PI-line section, where the shunt capacitor are determined by the discretization sampling time and the inductor value. When sampling time are very small, and inductor are large, the introduced parasitic capacitor can be neglected.
Two half Stubline components must be connected through transceiver elements (or real-time simulator I/Os) to represent a stubline. Stubline parameters must be the same in both components. The round trip latency refers to the number of sampling time required to reach and return from another half stubline. For the digital simulation of the model on one simulator on CPU, round trip latency should be 3. For simulation on CPU/FPGA, round trip latency should be between 2 and 3, depending of the implementation. For the simulation on 2 simulators, the actual round trip latency includes the delay in I/O drivers.
