DP_IMPORT - Add a new data-path component inside the current data-path.
#include <fpgen.h>
void DP_IMPORT(
char *ModelName, /* Figure/model name. */
char *InstName, /* Instance name. */
char *SigList , /* List of signals names. */
EOL);
ModelNameThe data-path object model name.
InstNameName to be given to the new instance.
SigList List of signals to be linked to the connectors of the instance. Notice that power supply signals *vdd* and *vss* must be ommited in the above list. They are detected in the model connector list and automatically inserted at the right place in the signal list.
The DP_IMPORT function allow the designer to include in the current data-path various customized components. At this time, only three type are recognized. The two first are heterogeneous operators and sub data-paths, they consist in netlists that must respect the rules given for the place and route tool dpr. In the preceeding cases DP_IMPORT checks for the netlist validity. For more informations about the data-path netlist constraints, see dpr. The last case is custom blocs, such blocs are detected when a layout associated with the model is found on the disk. For these the DP_IMPORT function run blindly, assuming that the layout is correct regarding the bit-slice requirements.
#include <genlib.h>
#include <fpgen.h>
