Step (2.5.1) is placed into the described software data flow graph user software data flow diagram model of drawing in the district to the software basic module in the software module storehouse and draws,
Step (2.5.2) is encapsulated as described software composite module to the part software model of described software data flow graph model on demand and adds in described software module storehouse,
Step (2.5.3) is transferred to the composite module described in step (2.5.2) described software data flow graph and is drawn and be used for the data flow diagram model in the district and draw from described software module storehouse,
Step (2.5.4) is placed into hardware topology figure and hardware resource figure to the hardware basic module in described hardware module storehouse and draws and be used for hardware topology figure in the district and the hardware resource graph model is drawn,
Wherein, described software model refers to software data flow graph model,
Described hardware model refers to hardware topology graph model or hardware resource graph model,
Step (2.6), after the user chooses software basic module in described software data flow graph, be dragged and dropped on the hardware computing node of described hardware topology figure, described program task allocation map module is presented at the allocation map relation that is used to specify in described allocation map relational result viewing area automatically, perhaps is mapped to the basic module assignment of described software on the hardware computing node of hardware resource figure and is presented in described allocation map relational result viewing area.
2. the graphical modeling method of a kind of software and hardware system CAD according to claim 1, is characterized in that, also comprises in step (2.5.4): the part hardware model in described hardware topology figure is encapsulated as the hardware composite module adds in the hardware module storehouse.
3. the graphical modeling method of a kind of software and hardware system CAD according to claim 1, it is characterized in that, in the software/hardware module library, also comprise: the user coordinates the direct modified module of database management tools or management software/hardware module library by system management facility or text editor.
4. the graphical modeling method of a kind of software and hardware system CAD according to claim 1, is characterized in that, in the drawing MBM, also comprises: the user directly revises parameter configuration files by system management facility or text editor.
