Signal test point detection method, signal test point detection system and related components

Abstract

The invention discloses a signal test point detection method which is applied to a detection tool and comprises the following steps: acquiring a PCB file; receiving a signal line selection instructionand SI information, and determining a signal line and a receiving end chip in the PCB file according to the signal line selection instruction and the SI information; and acquiring test information ofthe signal line, and adding a test point on the signal line according to the test information and the routing length specification of the test point from the receiving end chip. The influence on thesignal integrity performance can be reduced, signal test point detection is completed by the detection tool, and compared with manual detection, a large amount of working hours can be reduced, and thedetection efficiency and reliability are improved. The invention further discloses a signal test point detection system, electronic equipment and a computer readable storage medium, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of signal detection, in particular to a signal test point detection method, system and related components. Background technique [0002] In the research and development of servers, storage, etc., signal testing is an essential part to ensure the normal operation of hardware systems. But in some cases, the signal test cannot be carried out, such as some signals that need to be measured by an oscilloscope. If a test point is added to the trace, the oscilloscope will not be able to spot-test. Based on this, it is necessary to manually summarize the signals that need to be measured by an oscilloscope, and determine the measurement points on the signal line, and carry out PCB design according to the requirements of SI. However, considering that adding measurement points will reduce the signal integrity performance, and adding measurement points The location may require multiple attempts to meet the actual engin...

Based on this, it is necessary to manually summarize the signals that need to be measured by an oscilloscope, and determine the measurement points on the signal line, and carry out PCB design according to the requirements of SI. However, considering that adding measurement points will reduce the signal integrity performance, and adding measurement points The location may require multiple attempts to meet the actual engineering needs. Manual design and inspection are cumbersome and there will be omissions, which will reduce test efficiency and reliability.
