Abstract

The invention discloses a portable Space Wire router test system and a test method. According to the system, the FPGA is matched with the trigger button and the LED indicator lamp, after the system is powered on, a tester can start testing only by pressing the trigger button, and the LED indicator lamp visually displays whether a test result is correct or not, so that the practical operability is high. Compared with a traditional board-level test verification platform, the system has the advantages that a test PC (Personal Computer), interface software and complex physical connection lines are reduced, and the test can be carried out only by providing a voltage-stabilized power supply. The test system has a certain anti-static capability, is convenient to carry, can be used in various application places, and has strong applicability; the system provides a portable demonstration platform for application and popularization of the Space Wire bus. A precedent and a test verification platform are provided for a domestic road of the Space Wire router, and early-stage test verification is provided for application of the Space Wire bus as a space bus technology suitable for the space environment.

Description

[0001] 【Technical field】 [0002] 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. [0003] 【Background technique】 [0004] 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. [0005] 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 a...
