Abstract

The invention discloses a method for performing model simulation on custom hardware by using Simulink. The method comprises the following steps of: compiling a C MEX S file of the custom hardware, and generating a C MEX S file name.mexw32 file in an MATLAB command window according to a mex command; establishing a new model file comprising an S-function module of the custom hardware in the simulink, and packaging the S-function module of the custom hardware to ensure that a connected is established between the C MEX S file and the C MEX S file name.mexw32 file, and a panel and a dialog box of the S-function module of the custom hardware are generated; editing and compiling the model file to obtain MODEL.RTW of the model file; during the simulation of Matlab / simulink, popping up the dialog box of the S-function module of the custom hardware, inputting corresponding parameters from the dialog box and then submitting the parameters; and running a Start Simulation command to output a simulation graph. The invention also discloses a method for performing model code generation on the custom hardware by using the Simulink. The method can be used for performing the model simulation and the code generation on the custom hardware by using the Simulink, so that the time for system development is saved.

Description

technical field [0001] The invention relates to a method for model-based development in the field of automobile engineering, in particular to a method for using Simulink to perform model simulation and code generation on customized hardware. Background technique [0002] At present, the design method of Model-Based Development (MBD) has been more and more familiar and applied in engineering fields such as automobile and aerospace. Using the model-based V-type development method can realize rapid prototype simulation of the controller model, hardware-in-the-loop simulation, and model-based automatic code generation. The development environment commonly used today is the Matlab / Simulink modeling environment. Using the RTW (RealTime Workshop) software package in Matlab, automatic code generation based on the model can be realized. RTW provides multiple target configurations suitable for different application development environments. However, the hardware model set in Simulin...

Problems solved by technology

However, the hardware model set in Simulink is limited, and Simulink cannot be used to perform model-in-the-loop simulation of customized hardware. In this way, when performing hardware-in-the-loop simulation without setting a hardware model in Simulink, every time the system personnel change the hardware parameter configuration, it is necessary to Software personnel modify the source code of the hardware device driver, which will consume a lot of time for system development
