Block Designs are complex subsystem designs made up of interconnected IP cores, that can either serve as stand-alone designs, or be integrated into other designs. Block Designs, or diagrams, can be created with the IP integrator of the Vivado Design Suite. They can be created interactively, on the canvas of the IP integrator in the Vivado Design Suite IDE, or interactively using Tcl commands.
The Block Design diagram objects are structurally very similar to the netlist objects previously described. The relationships between the different design objects that make up Block Designs, or diagrams, are illustrated in Figure 1-2.
As seen in the figure above, the block diagram objects include:
