SIMULATOR ARCHITECTURE
High-performance FPGA architecture
At the heart of the OP4300-IO unit, there is a high-performance AMD KRIA™ K26 System-on-Module (SOM). The I/Os are fixed and carefully selected to cover most of our clients’ needs. A total of 6 DB37 I/O connectors are located on the top of the unit offering access to up to the 96 digital and analog I/Os.
Communication between the target computer and the OP4300-IO FPGA is achieved by an SFP optical fiber link using OPAL-RT’s MuSE communication protocol. An Ethernet port allows connecting to the facility network. Other ports are present and reserved for future use.
