HSR-PRP Switch (HPS) is an IP Core for the implementation of High-availability Seamless Redundancy and Parallel Redundancy Protocol (HSR and PRP version 3, IEC 62439-3-Clause 5 and 4 respectively) standards for Reliable Ethernet communications. HSR-PRP Switch is a full hardware solution that can be implemented on a low-cost FPGA.
It is a flexible solution for the Energy Market Equipment that will be connected to HSR rings, PRP Lans or will work as Network bridges in the context of IEC 61850.
HPS is supported on the following Xilinx FPGA Families:
- 6-Series (Spartan, Virtex)
- 7-Series (Zynq, Spartan, Artix, Kintex, Virtex)
- Ultrascale (Kintex, Virtex)
- Ultrascale+ (Zynq MPSoC, Kintex, Virtex)
- HSR/PRP Switch IP Core for Xilinx Vivado Tool -
HPS is designed to be easily integrated in your FPGA designs by taking advantage of the new Xilinx Vivado Tool, that allows to use the IP Cores in a graphical user interface and configure IP parameters in an easy way.
HSR-PRP Switch IP core key features:
- Fast Ethernet and Gigabit Ethernet.
- Full-Duplex Ethernet 10/100/1000.
- Half-Duplex Ethernet 10/100.
- It switches frames by hardware. This feature offers high switching speeds, needed to fulfill the Maximum Allowed Age and Data Integrity set for Process Bus and Inter-bay Bus in Electric Substation Automation
- The processing architecture has been designed specifically for HSR/PRP. Forwarding latencies in range of 500ns for Gigabit Ethernet
- It is an all-hardware. There is no need for on-chip microprocessor nor software stack
- It has been optimized to require few logic resources in order to allow the implementation on low-cost FPGA devices
- It supports IEEE 1588-2008 v2 combined with SoC-e 1588 IP cores
- It can be used to implement End-Node DAN, RedBox or QuadBox functionalities
- It has been provided with a single flag that switches between PRP and HSR modes by software
- It includes complete statistics and error registers for each port integrated (Network Supervision)
- Jumbo Frame Management.
- Supported HSR modes: H, N, T, U,X
- Supported PRP modes: Duplicates Discard, Duplicates Accept
- HSR-HSR, HSR-PRP supported modes for seamless PRP-HSR networks merging and Quadbox operation
- VLAN support and HSR Rings id
- Evaluation Designs for Spartan-6 and Zynq devices
- SMNP and MIB Table available
- Configuration-over-Ethernet (COE): Full access to internal registers through the same Ethernet link that connects to the CPU
- Dynamic Bitstream Configuration: Allows changing remotely the functionality of the FPGA
HSR-PRP Switch IP core customizable features for optimum resources/functionalities trade off:
