To combine your hardware and software diagrams into a common diagram for viewing during simulation, do the following: Note, it is recommended to make theses changes to copies of your actual model and DFG files, because the modifications render your files unbuildable. However, if you point the simulation viewer (SimView) at them, you will see your hardware and software side-by-side simultaneously. 1. Copy your hardware and software diagram files to specially named copies. Example: cp arch.sim arch_hwsw.sim cp flow.dfg flow_hwsw.dfg 1. Modify your copied DFG file (flow_hwsw.dfg). a.) Change to everywhere. b.) Change to . 2. Edit your copied hardware file (arch_hwsw.sim). a.) %include your flow_hwsw.dfg file. (By reference.) b.) Instantiate your DFG graph somewhere on your top-level graph. 3. Point your SimView at your modified file: Example: setenv SIM_GRAPH arch_hwsw.sim Then invoke simulation as normal: sim.exe
