Abstract

The invention relates to the technical field of computer system simulation, in particular to a simulation system based on a hierarchical transaction-level modeling protocol. The simulation system based on the hierarchical transaction-level modeling protocol comprises a control module, a data module and an adaptation module, the control module is a central management unit, is connected with the data module and the adaptive module through a control bus, and is used for managing load information of each node and realizing a time sequence management mechanism; the data module is a core communication hub, comprises a transaction-level modeling protocol stack and is connected with the adaptation module through a transaction bus; and the adaptive module is an equipment interaction layer, comprises a protocol conversion unit, is connected with the external simulation module or equipment through the corresponding protocol conversion unit, and is used for converting a signal connected with the physical bus into a transaction bus signal. According to the simulation system based on the hierarchical transaction-level modeling protocol, the simulation time precision is improved, the expansibility is improved, and the development and maintenance cost is reduced while the simulation efficiency is effectively improved.
