Problems solved by technology

[0002] The functional verification of an integrated circuit must cover all the actual application scenarios of the circuit. The existence of different verification scenarios in all verification sets of the circuit is often not mutually exclusive, so there will be repetitive work in the process of developing test items, resulting in a waste of manpower and time. waste

Embodiment Construction

[0012] The specific implementation manners of the present invention will be described clearly and completely below in conjunction with the accompanying drawings.

[0013] The present invention is a verification method for a USB controller in an on-chip processor, the verification method is based on a test platform, the test platform includes a processor model 1, a USB controller model 2 and a handshake model 3, the test See platform figure 2 . The verification methods include:

[0014] 1) Processor model 1 controls the entire simulation process. Among them, the processor model 1 in the test platform loads the verification items required by the current verification scene. The verification items are composed of command combinations. When the simulation starts, the processor model 1 sends the initialization command 201, the reset command 202, and creates the sending and receiving buffer in sequence. Instruction 203, filling data instruction 204, all instructions are passed to...

Abstract

The invention belongs to the technical field of integrated circuit design, and relates to a verification method for a USB controller in an on-chip processor. The verification method is based on a testplatform. The test platform comprises a processor model (1), a USB controller model (2) and a handshake model (3). The verification method comprises the steps that 1) the processor model (1) controlsthe whole simulation process; 2) the handshake model (3) controls instruction transfer between the processor model (1) and the USB controller model (2); and 3) the USB controller model (3) executes all instructions developed in the verification environment. The invention provides a method for verifying modularization of models. Underlying verification components are developed according to requirements of a verification scene, the underlying verification components only need to be combined together in test item construction, and the construction of the verification scene is completed quickly.The method can improve the verification efficiency and shorten the time required by the whole verification stage.

Description

technical field [0001] The invention belongs to the technical field of integrated circuit design and relates to a verification method for a USB controller in an on-chip processor. Background technique [0002] The functional verification of an integrated circuit must cover all the actual application scenarios of the circuit. The existence of different verification scenarios in all verification sets of the circuit is often not mutually exclusive, so there will be repetitive work in the process of developing test items, resulting in a waste of manpower and time. waste. Contents of the invention [0003] The purpose of the present invention is: the present invention proposes a verification method for the USB controller in the on-chip processor, through the modularized verification method, the repetitive work in the development process of the verification item is avoided. [0004] The technical solution of the present invention is: a verification method for a USB controller i...
