NetModule presents NetJury, a test tool with programmable FPGA logic aimed at testing real-time Ethernet protocols, for example for conformity with the IEC 62439 PRP protocol. The tool can be used to check whether end devices from different manufacturers (e.g. Siemens, ABB, Hirschmann) comply with the standard and are interoperable. Tuning and regression tests, error-based stress tests and error tracking as well as development tests round off the areas of application. In addition to a Xilinx Zynq-7000 module, the device integrates 1 Gbyte DDR SDRAM, 16 Mbyte QSPI Flash, micro SDHC slot, four Gigabit Ethernet ports and an Ethernet management port. The hardware enables packet analysis and generation under real-time conditions in the nanosecond range. As a further feature, the test tool offers users the 'Deploy your Own' strategy: because the processor system runs Linux, standard Linux applications are supported. This means that users can continue to use existing test applications and expand them with additional script-based real-time tests.
