If you want to access the AXI block RAM Controller from microblaze_riscv_0, you can exclude the other slaves from the microblaze_riscv_0 memory space. This can be done in the
Address Editor window.
As can be seen in the following figure, the microblaze_riscv_0 memory space has three unmapped slaves.
Figure 1. microblaze_riscv_0 Memory Map
- Assign addresses to all the unmapped slaves by selecting them, right-clicking, and selecting Assign Address from the context menu.
- Exclude the unwanted slaves from the memory map of
microblaze_1by selecting them in the Address Editor window. Right-click and select .
After you complete the design in this way, the rest of the design flow is the same as any other Block design flow.
