A method and device for determining message timeout based on multiprocessor system simulation

Abstract

The invention discloses a message timeout determining method and device based on multi-processor system simulation. A multi-processor system comprises a plurality of message-level timers and a system-level timer; different message-level timers correspond to different messages; each message-level timer is used for recording the time interval of a corresponding message from sending to processing completion; and the system-level timer is used for recording the processing completion time interval of two sequentially processed messages. The method comprises the following steps of: monitoring the timing duration of all the started message-level timers and the timing duration of the started system-level timer; and determining message timeout if the fact that the timing duration of any message-level timer reaches a pre-set first threshold value or the timing duration of the system-level timer reaches a pre-set second threshold value is monitored. By means of the technical scheme provided in the embodiment of the invention, the timeout message judgement duration when the system is not in the worst condition can be effectively shortened; and thus, the verification duration is shortened.

Description

technical field [0001] The invention relates to the field of computer application technology, in particular to a method and device for determining message timeout based on multiprocessor system simulation. Background technique [0002] With the continuous development of chip process technology and chip application technology, the complexity of chips continues to increase. Correspondingly, the complexity of chip verification work also continues to increase. The time spent on verification work has increasingly become the bottleneck of the chip development cycle. Shortening the duration of each part of the verification work and avoiding repeated invalid verification work has become an important direction for optimizing chip verification work and shortening the chip development cycle. [0003] For the multi-processor system simulation verification of message processing, there is often a dependence on message processing between processors. As the number of processors and the num...

Problems solved by technology

With the increase in the number of processors and the number of messages sending messages simultaneously in a multi-processor system, the processing time for a specific single message in the entire multi-processing system is likely to increase significantly
