Tutorial Overview In the last tutorial we implemented the embedded Tri-mode Ethernet MAC and tested it by looping back Ethernet packets and monitoring them with Wireshark. In this tutorial, we will again implement the EMAC but this time we will link it to an Aurora core, to implement an Aurora to Ethernet Bridge. With the bridge, we can link two PCs as shown in the diagram below. To connect the EMAC and Aurora cores we have to use two FIFOs to cross clock domains. [Read More]

Tutorial Overview In some FPGA designs, it is necessary to interface two devices that operate in different clock domains. One solution to crossing from one clock domain to another is by using FIFOs with independent read and write clocks. In this tutorial, we will generate FIFOs with independent read and write clocks, and non-symmetric aspect ratios. This tutorial was written for the Aurora to Ethernet Bridge project in which we want to interface the Ethernet MAC to the Aurora core. [Read More]

Tutorial Overview In this tutorial, we will generate an Aurora IP core using the Xilinx CORE Generator version 10.1. The Aurora core can be used as a high-speed serial communications link for connecting multiple FPGAs or interfacing to other serial devices. Requirements To generate the Aurora core with CORE Generator, you will first need to register with Xilinx to obtain a license to use the Aurora core. It is a free and simple process that involves accepting a license agreement. [Read More]

Overview In this tutorial we will create a peripheral containing the Aurora core to implement a high speed serial transceiver with a RocketIO MGT. It will be an improved version of the Aurora transceiver developed in the tutorial titled Create an Aurora Transceiver. The improvement is achieved by connecting the peripheral to the PLB rather than the OPB, which allows much faster data transfer by virtue of a wider bus and Direct Memory Access capability.

Overview In this tutorial we will create a peripheral containing the Aurora core to implement a high speed serial transceiver with a RocketIO MGT. The peripheral can be used to connect two XUPV2P boards using the SATA connectors and transfer data between them at 1.5Gbps. To test the design using only one XUPV2P board, we will instantiate two Aurora peripherals, assign them to different RocketIO MGTs and place a SATA cable between them to create a loop-back connection.
