Project and Top-Level Model
An SoC application model developed using the SoC Blockset™combines multiple subsystems and reference models. Each subsystem and reference model maps to a particular feature of an SoC device. Organization of the models and shared configuration settings requires a Simulink® project.
Create a new SoC Blockset project named
SampleSoCApplication. Creating a new project automatically creates a new project folder with the same name. For more information on creating projects, see Create a New Project From a Folder.
Open a new Simulink model. Save the model as
soc_hwsw_top.slxinto the project folder.
In MATLAB®, on the Project tab, in the Tools section, select Run Checks > Add Files and add the
soc_hwsw_top.slxmodel file to the project.
In Simulink, configure the
soc_hwsw_top.slxmodel to as an SoC application. On the Apps tab, under Setup to Run on Hardware, click System on Chip (SoC).
In the System on Chip (SoC) pop-up window, select Hardware Board > Xilinx Zynq ZC706 evaluation kit. Click Finish.
You can optionally choose any of the available hardware boards based to suit your system requirements.
On the System on Chip tab, click Hardware Settings. On the Configuration Parameters dialog box, in the Solver tab, set Solver selection > Type to
Variable-step. Click OK.
Create three box areas and label them as
Processor. For more information on creating box areas, see Box and Label Areas of a Model. In the following sections, these areas are populated for various aspects of your SoC application.
Create a new MATLAB function to initialize variables used throughout the project.
function soc_hwsw_init % Initialize the model wide variables and set them in base workspace. SourceSTime = 1e-7; FrameSize = 1000; ProcSTime = SourceSTime*FrameSize; FPGASTime = SourceSTime; FPGAFrameSize = 1; assignin('base','ProcSTime',ProcSTime); assignin('base','FPGASTime',FPGASTime); assignin('base','SourceSTime',SourceSTime); assignin('base','FPGAFrameSize',FPGAFrameSize); assignin('base','FrameSize',FrameSize); end
In the project folder, save the file as
soc_hwsw_init.min a new subfolder,
utilitiesand add the file to project.
