If you want to access the AXI block RAM Controller from microblaze_1, you can exclude the other slaves from the microblaze_1 memory space. This can be done in the address editor. As can be seen in the following figure, the microblaze_1 memory space has three unmapped slaves.

Figure 1. microblaze_1 Memory Map

  1. First, assign addresses to all the unmapped slaves by selecting them, right-clicking, and selecting Assign Address from the context menu.

  2. Next, "exclude" the unwanted slaves from the memory map of microblaze_1 by selecting them in the address editor, right-clicking, and selecting Exclude Segment, as shown in the following figure.

    The address editor now looks as follows.

After you complete the design in this way, the rest of the design flow is the same as any other Block design flow.
