Abstract

The invention discloses a portable Space Wire router testing system and testing method; the system uses FPGA with a trigger button and an LED indicator light. The light visually shows whether the test result is correct or not, which makes it more practical. Compared with the traditional board-level test and verification platform, this system reduces the number of test PCs, interface software, and complex physical connections, and only needs to provide a regulated power supply for testing. The test system has a certain anti-static ability, is easy to carry, can be used in various application places, and has strong applicability; this system provides a portable demonstration platform for the application and promotion of Space Wire bus, and paves the way for the localization of Space Wire routers Provide a precedent and test verification platform, and provide preliminary test verification for Space Wire bus as a space bus technology application suitable for aerospace environments.

Description

【Technical field】 [0001] The invention belongs to the field of reliability and consistency of integrated circuit quality, and relates to a portable Space Wire router test system and a test method. 【Background technique】 [0002] The Space Wire bus is a set of space bus standards suitable for aerospace environments developed by the European Space Agency (ESA) and a number of scientific research units based on two commercial standards IEEE 1355-1995 and IEEE 1596.3 in 2003. It is a point-to-point High-speed transmission links have been applied in space science missions organized by many countries. [0003] LC7910 is a domestic Space Wire router circuit developed in the nuclear high-level project "200Mbps radiation-resistant high-speed bus control device", providing 8 bidirectional full-duplex Space Wire links, the transmission rate is 2Mbps-200Mbps External FIFO interface, support path address routing, logical address routing, group adaptive routing, priority arbitration, etc...
