Description

technical field [0001] The invention relates to the verification field of standard protocol interfaces, in particular to an interface protocol verification method and system of a multi-interface protocol chip. Background technique [0002] With the increasingly rich application requirements, the types of interface protocols supported by embedded chips are gradually increasing. For example, in addition to supporting conventional various storage type interface protocols, embedded chips also support serial ports, host , bus), SPI (Serial Peripheral Interface, Serial Peripheral Interface), UTOPIA (Universal Test & Operations PHY Interface for ATM, ATM’s general test and operation PHY interface) and other protocols. In order to ensure the correctness and reliability of the external data and control interaction of the designed chip, a comprehensive verification of the various supported protocols is required. [0003] The compatibility verification method of the independent forwar...

Problems solved by technology

The problem with this method is that the model that interacts with the interface to be tested is also a software model, and its correctness has yet to be verified; in addition, although the software simulation that adds timing information to back-annotation is more in line with the actual situation, the simulation The speed is slow; the task of comprehensively verifying various interface protocols through back-annotation simulation is heavy

When the chip to be verified has a multi-interface protocol, various verification platforms with different peripheral circuits need to be built to achieve complete verification. The hardware overhead is high, and the platform and driver need to be replaced repeatedly during verification. The verification efficiency is low, which increases the verification cost. the complexity
