Embodiment Construction

[0031] Such as Figure 1 to Figure 6 As specifically shown, in the embodiment of the present invention, a power tree is first established, and the specific steps are as follows:

[0032] 1) Fill in the input voltage as 5V and the input current as 3A;

[0033] 2) Fill in the network name as VCC_5V;

[0034] 3) Choose to add a power supply chip on the VCC_5V network, input the model as LTM4615, call out the information template of this chip, and automatically display the model as LTM4615, the energy efficiency is 95%, and fill in the input voltage as 5V, input current as 1A, bit number It is D2, the supply voltage is 3.3V, and the maximum supply current is 2A;

[0035] 4) Fill in the network name VCC_3.3V after the D2 template with a supply voltage of 3.3V;

[0036] 5) Choose to add a passive device on the VCC_3.3V network, enter the model as PB1608-600-3A, call up the information template of this chip, and automatically display the model as PB1608-600-3A, the DC impedance is...

Abstract

The invention belongs to the field of electronic equipment power supply design, and designs a power supply direct current design automatic analysis method. Semi-automatic power supply tree establishment is realized by establishing a device library and presetting inherent information of a chip: a) filling in an input power supply network name after inputting information; B) selecting the type of the next node after the network name: a power supply chip / a passive device / a load chip; C) finding a corresponding device information base according to the selected type; D) if the device is a power supply chip / a passive device, inputting the type of the device, and automatically calling a corresponding information template; If the chip is a load chip, the type of the input device and the power supply voltage are input, and a corresponding information template is automatically called; Wherein the input information cannot be modified, and only the to-be-input information can be modified; And e) supplementing to-be-input information, selectively filling the bit numbers, and finally, quickly and accurately analyzing the correctness of the whole power supply design through an automatic power supply analysis method, and directly positioning the design error.

Description

technical field [0001] The invention is an automatic analysis method for the DC design of the power supply of electronic equipment, which can clearly express the design situation of the power supply and analyze whether the design of the power supply is reasonable. The technology belongs to the field of power supply design of electronic equipment. Background technique [0002] In electronic equipment, power supply design is one of the important factors that determine product quality. With the continuous development of electronic equipment, equipment processing performance requirements are getting higher and higher, and they are also becoming more and more miniaturized, which leads to more complicated power supply design. Designing and analyzing the power supply of electronic equipment is becoming more and more complex. [0003] At present, the power supply analysis and design method commonly used in the industry usually uses tables. The table method can only briefly express ...
