The Aurora protocol is a lightweight serial protocol developed by Xilinx that is suitable for high speed point-to-point communication links. Support for the Aurora protocol exist for PB5 and NovaCor based RTDS Simulators and is available within both the main timestep and small timestep simulation environments. Aurora specifications for the PB5 and NovaCor hardwares are similar but slight differences do exist. The overview provided here focuses on the NovaCor implementation.
The RTDS Simulator’s Aurora protocol implementation allows the bi-directional exchange of 32-bit integers or floating point numbers between the simulator and another Aurora protocol compatible device. Signals are exchanged via a fiber optic cable.
The ability to output or read-in Aurora formatted packets must be licenced for each PB5 card or NovaCor chassis. Each license allows for interconnections over 4 different fiber optic cables. Each fiber optic connection supports the output of 1-64 numbers as well as the input of 1-64 numbers.
In order to read or write Aurora data to/from a fiber optic cable, either the mainstep or small timestep Aurora components must be used in DRAFT. Both of these icons are shown below and can be found if the keyword ‘aurora’ is used to search the master library.
