AI Technical Summary

Technical Problem

The prior art is difficult to implement precise physical clock timing control of simulation events in the SystemC simulation model, making it difficult for developers to monitor timeouts.

Method used

After the SystemC worker thread sets the expected timeout timeout of the target simulation workflow, an operating system timing thread is created, and the target simulation workflow is timed out based on the reception order of the first and second flag update notifications, and combined with the physical clock timing of the operating system timing thread, high-precision timeout monitoring is achieved.

Benefits of technology

It realizes high-precision physical clock timing control of the SystemC simulation model, which can conveniently and accurately monitor the timeout status of any simulation process without affecting the original execution order and performance of the simulation model.

Abstract

The invention discloses a simulation workflow timeout monitoring method and device, equipment and a medium, relates to the technical field of computers, is applied to a SystemC timing thread, and comprises the following steps: after a SystemC working thread sets an expected timeout duration of a target simulation workflow, creating an operating system timing thread according to a flow start signal sent by the working thread; setting the timing duration of the timing thread of the operating system based on the expected timeout duration; judging whether the target simulation workflow is overtime or not according to the receiving sequence of the first mark updating notice and the second mark updating notice, and executing corresponding processing operation based on a judgment result; the first mark update notification is an update notification of a completion mark corresponding to timing completed by the timing thread of the operating system based on the timing duration; the second mark update notification is an update notification of a corresponding end mark when the SystemC working thread finishes executing the target simulation working process. According to the invention, high-precision physical clock timing control can be carried out.
