Embodiment Construction

[0021] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0022] A self-test platform for testing the serial RapidIO network switching module shown in this embodiment can test the port connection status of the serial RapidIO network switching module without the need for a system integration joint test environment and other terminal node modules, and exchange transmission Delay, end-to-end transmission bandwidth, port transmission bit error rate and automatic optimization of signal quality. This embodiment can greatly improve the qualified rate of ex-factory products, and also provides a means for other RapidIO terminal node modules in the system to isolate faults and serve the joint test of the whole machine system.

[0023] A self-test platform for testing a serial RapidIO network switch module shown in this embodiment includes baseboard hardware and test software. Backplane hardware such as figu...

Abstract

The invention discloses a self-test platform for testing a serial RapidIO network switching module, and the platform comprises bottom plate hardware and test software, and the bottom plate hardware comprises a plurality of port pins, two FPGA chips, and two debugging serial ports. The port pins are used for leading each outer outgoing port of the switching module to a bottom plate, and a self-loopback relation is formed between any two port pins by adopting an external self-loopback mode; the debugging serial port is used for outputting a test request to the FPGA chip; one SRIO interface is led out of the two FPGA chips to be connected with any port pin in an external jumper mode according to test requirements, and the same test software resides in the two FPGAs; and the test software comprises a switch driver, a RapidIO controller and a function test unit and is used for completing various test items. Under the condition of not depending on a system testing environment, the platform is suitable for testing functions and performances of various customized serial RapidIO network switching modules.

Description

technical field [0001] The invention belongs to the field of high-speed interconnection of embedded systems, in particular to a self-testing platform for testing the functions and performances of serial RapidIO network switching modules of modern high-performance embedded systems. Background technique [0002] At present, with major changes in I / O interconnection technology and architecture, emerging interconnection technologies are emerging. As an open standard, the RapidIO interconnect architecture meets the extensive application requirements of embedded infrastructure. RapidIO technology mostly adopts a switch-based interconnection topology, and RapidIO endpoint devices are not directly interconnected but interconnected through RapidIO switches. The communication links of multiple RapidIO end devices in the system are organized by RapidIO switches, which can realize arbitrary interconnection and concurrent transmission of the RapidIO system, and double the system bandwid...
