Abstract

The invention provides a PECI bus verification method and system supporting multiple slaves. The method comprises the steps that 1, models are defined, wherein a host model, a slave model and a test environment top are defined, and the host model comprises a read-write process unit; 2, the test environment top generates test excitation, and the test excitation is input into an input port of the host model; 3, the host model creates a read-write process task to a to-be-tested PECI bus interface according to the test excitation through the read-write process unit; 4, the to-be-tested PECI bus interface sends the read-write process task to the slave model through a PECI bus; 5, the slave model responds to the read-write process task and sends returned data, and the returned data arrives at the host model through the to-be-tested PECI bus interface; 6, the host model outputs the returned data to the test environment top from an output port; and 7, the test environment top judges the correctness of the returned data according to the test excitation, and whether the to-be-tested PECI bus interface has an error is judged.

Description

technical field [0001] The invention belongs to the field of hardware testing, and in particular relates to a PECI bus verification method and system supporting multiple slaves. Background technique [0002] PECI is a new-generation digital interface proposed by Intel, which is a dedicated single-wire bus between the processor and the system stability monitoring device. It is used between BMC and processor in the server field to read CPU temperature and read and write related device information. The transmission of the PECI bus is based on specific commands of the protocol. The format of the command is divided into address, write length, read length, write data, FCS, and read data. There is no method for verifying the PECI bus in the prior art. [0003] This is the deficiency of the prior art. Therefore, aiming at the above-mentioned defects in the prior art, it is very necessary to provide a PECI bus verification method and system supporting multiple slaves. Contents of...
