Power supply time sequence simulation generation device and control method

Abstract

The invention discloses a power supply time sequence simulation generation device and a power supply time sequence control method. The device comprises a control module, two gear dial switches connected with input / output (IO) ports of the control module, and four numerical value dial switches connected with IO ports of the control module. Power supply time sequences in the power supply time sequence simulation generation device are adjustable; the time of each path of power supply output can be controlled to be accurately adjustable in a certain range, so that various possible power supply time sequences in the starting, restarting and standby processes of an electronic system can be simulated, and the influence of the power supply time sequences on the working stability of the electronic system is effectively and quickly found; and therefore, an engineer can well improve the design of a power supply system at the early stage of research and development, and a machine with the power supply time sequence failure probability of one hundredth to ten thousandth can be quickly found when circuit boards are produced in batches.

Description

technical field [0001] The invention belongs to the field of audio and video electronic products, and more specifically relates to a power supply timing simulation generation device and a control method thereof. Background technique [0002] With the development and popularization of electronic information technology, various electronic products are manufactured in an explosive manner. Today, as the integration of electronic chips is getting higher and higher, the power supply of the circuit system is extremely important. How to ensure that the designed products can work stably in various harsh and complex environments has become a difficult problem. Many electronic products have no problems in the early stage of research and development. However, as the products are sold to various target markets around the world, and the external environment of each market is different, some products often appear to be unstable, cannot be turned on, and have been restarted many times.
