Problems solved by technology

[0004] The disadvantage of the existing technology is: because the monitoring software and the monitored software receive data at the same cycle, the monitoring cycle is short. If it is judged that there is a disconnection, an alarm will be thrown according to the situation. Such an operation is very important for the control of the entire device. For the software, it will consume a lot of system resources, and it is also a big waste of software performance.
In addition, this method will appear that when the data read by the monitoring software is about to start or end to change (that is, the rising or falling edge of the data transmission waveform), the read data will not change, and it will always be the same value, so will lead to misjudgment
Moreover, the higher the frequency of data reading, the greater the probability of reading errors, and the greater the probability of erroneous judgments.

Abstract

The invention provides a software disconnection monitoring method. The software disconnection monitoring method includes the following steps that software to be tested changes sent data with a first period T1 through a sending module; a receiving module obtains the sent data changed by the sending module with a second period T2, wherein N*T1<T2<(N+1)*T1 and N is a positive integer; whether the software to be tested undergoes disconnection or not is judged based on the obtained sent data. With the software disconnection monitoring method, the number of times in reading and writing the data is reduced, cost is saved, the error probability is greatly reduced, disconnection occurring is determined more effectively. The invention further provides a software disconnection monitoring system.

Description

technical field [0001] The invention relates to the technical field of semiconductors, in particular to a software disconnection monitoring system and method. Background technique [0002] In the fields of semiconductor production such as etching and solar energy, equipment-side software includes equipment control software, data acquisition software, and CTC (Cluster Tool Controller, cluster equipment controller) software, etc. These software need to keep connected, exchange data and various services, and coordinate to complete the production and product quality control of the entire equipment. These software are distributed on different computers, and data exchange is performed through the network. During the production process of the equipment, it is necessary to ensure that the connection of each software must be normal. The equipment-side control software is responsible for controlling the Wafer (wafer) etching process, recording various process parameters and sending t...
