Importing a System Generator Design into a Bigger System
The transcript should look similar to the following:
Adding System Generator Source into the Top-Level Design
The next two steps are used to synthesize the top_level design:
1. Launch ISE and reload the pre-generated top-level design ISE project at
~top_level/top_level.ise.
Note:
At this point, your Project Navigator should look like the figure below. Both spram_cw and
mac_fir_cw instances are instantiated at the top_level design. But since they are not located on the
same directory as the top-level design, Project Navigator puts a question mark next to each one of
them to indicate that it can not find these two instances / modules.

2. Add the System Generator source: under the Sources tab, right-click on
u_spram_cw -> Add Source…at
<ISE_Design_Suite_tree>/sysgen/examples/projnav/mult_diff_desig
