Abstract

A method and system for multi-thread collaborative simulation is provided in the embodiments of the present invention. The method for multi-thread collaborative simulation is characterized in that it comprises: a software module after startup obtains the process number of a hardware module and according to the process number creates a pipe communication way of communication with the hardware module; the software module interacts with the hardware module in the pipe communication way to enable the collaborative simulation of the software module and hardware module. The method is used to implement the collaborative simulation of software modules and hardware modules in a chip in the same environment.

Description

technical field [0001] Embodiments of the present invention relate to a multi-thread co-simulation method and system. Background technique [0002] At present, the chip design process is generally: the pre-research of the chip, the division of each functional module (such as software module, hardware module), the realization of specific modules, and then the debugging of each module. [0003] In the prior art, the debugging of the multi-threaded software module and the hardware module is not in the same simulation platform, for example, the multi-threaded software module is debugged through the corresponding first simulation platform, and the software module is modified according to the design requirements; the hardware module is passed through The corresponding second emulation platform is debugged, and the hardware module is redesigned and debugged as required. [0004] However, when the software modules and hardware modules debugged by the above method are integrated int...
