Aldec recently published a very descriptive example design for a high-performance, re-programmable network router/switch based on the company’s TySOM-2A-7Z030 embedded development board and an FMC-NET daughter card. The TySOM-2A-7Z030 incorporates a Xilinx Zynq Z-7030 SoC. The Zynq SoC’s dual-core Arm cortex-A9 MPCore processor runs the OpenWrt Linux distribution for embedded devices in this design. It’s a favorite for network switch developers. The design employs the programmable logic (PL) in the Zynq SoC to create four 1G/2.5G Ethernet MACs that connect to the FMC-NET card’s four Ethernet PHYs and a 10G Ethernet subsystem that connects to the FMC-NET card’s QSFP+ card cage.
