Verification method and verification system for interface controller

Abstract

The invention discloses a verification method and a verification system for an interface controller. The method comprises the steps of when any interface controller in a chip to be tested is verified, sending generated initial test data to a mirror image controller corresponding to the interface controller by using a simple drive program, triggering the mirror image controller to perform data format conversion on the initial test data to acquire first test data, and sending the first test data to the tested chip; receiving fourth test data returned by the mirror image controller, wherein the fourth test data is acquired through performing data format conversion on third test data by the mirror image controller, and the third test data is acquired through further performing data format conversion on second test data by the interface controller in the tested chip; comparing the initial test data with the fourth test data; and determining a verification result of the interface controller according to a comparison result. Therefore, the interface controllers with different protocols can be verified by using the data with simple protocols.

Description

Technical field [0001] The present invention relates to the field of data communication technology, in particular to a verification method and a verification system of an interface controller. Background technique [0002] In the process of chip design, multiple interfaces are usually configured for the chip. Take SOC (System On Chip, system on chip) as an example. figure 1 As shown, the SOC chip is provided with UART Controller (Universal Asynchronous Receiver / Transmitter Controller), SPI (Serial Peripheral Interface Controller) and I2C (Inter-Integrated Circuit Controller). , Inter-Integrated Circuit Interface Controller). When designing the SOC chip, it is necessary to verify the three built-in interface controllers. However, because different interfaces follow different protocols, when verifying the interface controller, it needs to be verified according to the interface protocol. The controller performs verification, that is, different driver programs and monitor programs n...

Problems solved by technology

When designing the SOC chip, it is necessary to verify the three built-in interface controllers. However, because different interfaces follow different protocols, when verifying the interface controller, it is necessary to verify the interface controllers according to the protocol of the interface. The controller is verified, that is, it is necessary to write different driver programs and monitor programs for different interfaces, which will increase the verification workload, etc.
