Verification method of multi-port multi-message type cross communication component

Abstract

The invention relates to a verification method for a multi-port multi-message type cross communication component. The verification method comprises the following steps: defining various data domains contained in various message types; defining each path of physical channel on each port; establishing a corresponding relationship between various message types and corresponding physical channels of each port according to actual design requirements; establishing a transmission reference model according to actual design requirements; generating a test sequence accommodating various message types, and injecting the test sequence into the reference model and an actually designed sending port; collecting message queues of message types acquired on the transmission reference model and an actually designed receiving port; and comparing the sequence of the transmission reference model and the actually designed received message queue with the domain correctness of each type of data contained in each received message type in the queue. According to the invention, the verification result is more accurate and convenient.

Description

technical field [0001] The invention relates to the technical field of processor chip simulation verification, in particular to a verification method of a multi-port multi-message type cross-communication component. Background technique [0002] With the continuous expansion of integrated circuit design scale and increasing design complexity, processor design is becoming more and more complex and its functions more diverse. Therefore, the correctness verification of processor chips becomes increasingly complex and difficult. This complexity, diversity, and difficulty can be reflected in the cross-communication of a large number of different types of messages between multiple ports within a single processor and among multiple processors, and it is necessary to ensure the cross-communication of multi-port and multi-message types correctness verification of components and speed up the verification process. [0003] In order to improve the performance of the processor, the mes...

Problems solved by technology

[0003] In order to improve the performance of the processor, the message type and the corresponding port interface protocol are often customized in the design of the processor, so the VIP (Verification Intellectual Property) based on the general bus protocol provided by the third party cannot be used, which greatly increases the verification cycle and correctness of the processor.
