Using the Interface

Follow the steps to create a new SC_Module. More details are provided using the below examples.

• Drag a SC_Sim block from Full Library > Hardware_Language > SystemC > SC_Sim.
• Now drag a SC_Cosim block from Full Library > Hardware_Language > SystemC > SC_Cosim.
• Configure the block parameters as follows:
1. SC_Module_Name is the name of the block or Source Code. The module name is typically the name of the top source code filename without the .ccp or .h extension.
2. SC_File_Path is the relative path of the Source Code.

                    For example: If VS_C_Library = C:\VisualSim\VS930\UserNativeC, then the path is SystemC/Source_Files/CPU_M.cpp.

• Next, configure the ports.
1. Add as many input and output ports as required. Multiports are not supported.
2. Configure the Remote Types to the corresponding types in SystemC. A list of the types are provided in Table 1 and Table 2.
• Execute from the Menu Bar; first Interface > Generate Wrapper and then Interface > Compile Wrapper.

• Now connect this block to the rest of the system.
• You should now be able to simulate the model.

Note: Using Object files

• If the code is better compiled as an object file, this can be imported into VisualSim by simply specifying the names of the object files. To do this, add a new parameter called Obj_Files to the SC_Cosim block. The parameter Obj_Files can contain space separated list of additional files which has to be linked to the build library.
