Real-time simulation system oriented to space-borne electronic system

Abstract

The invention provides a real-time simulation system oriented to a space-borne electronic system, relates to a simulation system, and aims at solving the problems of low simulation efficiency and poor adaptability of the conventional real-time simulation system oriented to a space-borne electronic system. The system comprises a test vector unit, a design simulation verification unit and a network control unit, wherein the test vector unit is used for introducing or establishing a system vector model, and simulating and verifying test input data of a VHDL (very-high-speed integrated circuit hardware description language) entity, and calculating and verifying output data of the VHDL entity; the design simulation verification unit is used for introducing in the VHDL entity, establishing an engineering file to be simulated and verified, controlling or calculating the input data of the network control unit, and outputting the result to the test vector unit through the network control unit; and the network control unit is used for controlling the whole simulation process through a network. The real-time simulation system oriented to the space-borne electronic system is suitable for real-time simulation of the space-borne electronic system.

Description

technical field [0001] The invention relates to a simulation system. Background technique [0002] At present, the mainstream design method of FPGA is to use VHDL and other hardware description languages ​​to write programs to realize functions. During the design process, it is necessary to repeatedly perform function-level simulation and real-time simulation verification to verify the correctness of the design. When the designed spaceborne electronic system is relatively complex, the functional-level simulation verification is time-consuming, which greatly lengthens the entire design cycle. To carry out functional simulation, it is first necessary to create a stimulus file, fully verify its function, manually assign values ​​to the input ports, and manually verify the correctness of the simulation results, and its efficiency is bound to be extremely low. And for a system with continuous input, continuous data input cannot be carried out comprehensively to check the correct...
