Abstract

The invention provides a bus checking method and device. The method comprises the following steps: determining a target chip to be examined in a single board according to a device list of the single board; according to pre-stored chip attribute information of chips in the single board, if it is confirmed that a bus needing to be examined exists in the target chip, pins of the existing bus are extracted from the chip attribute information of the target chip; according to the netlist of the single board, performing network series connection on pins corresponding to the extracted pin information of the bus to obtain a pin network; checking the pin network, and judging whether the pin network has pins with different attributes or not; and when the pins with different attributes exist in the pin network, determining that the target chip has a bus reverse connection condition. Therefore, the automatic checking of the bus is realized, the labor cost is saved, and the accuracy of the checking result is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a bus inspection method and device. Background technique [0002] Various types of buses are used in circuit design, including data buses, clock buses, etc., for communication between chips and modules. There are many types of buses, such as serial bus, parallel bus, single-ended bus, differential bus and so on. And no matter what kind of bus, it must follow the requirements of the same attribute docking in application. For example, the bus between two chips and modules must be clock-clock docking, data-data docking, positive (P) and positive (P) docking , the negative pole (N) is docked with the negative pole (N), if there is a reverse connection, the bus communication will fail. Therefore, when reviewing the schematic design, it is necessary to check whether there is a reverse connection of the bus to ensure the correctness of the circuit design. [0003...
