By default, Vitis HLS implements the AXI4 port with a 64-bit address bus. However, some devices such as the Zynq-7000 have a 32 bit address bus. In this case you can implement the AXI4 interface with a 32-bit address bus by disabling the
configuration option as follows:
- Select .
- In the Solution Settings dialog box, click the General category, and Edit the existing
config_interfacecommand, or click Add to add one.
- In the Edit or Add dialog box, select config_interface, and disable m_axi_addr64.
Important: When you disable the m_axi_addr64 option, Vitis HLS implements all AXI4 interfaces in the design with a 32-bit address bus.
