2013.2 Vivado IP Integrator- Zynq GP0 and GP1 ports should allow for 2GB address space access


According to Zynq TRM the address ranges for M_AX_GP0 and M_AXI_GP1 are 0x4000_0000 to 0x7FFF_FFFF and 0x8000_0000 to 0xBFFF_FFFF respectively.

This means that each has access to 1 GB of address space.
To achieve this using 2013.2 Vivado IPI, I enable both of the master GP ports, and I try to access an IP present in the PL side using a 2:1 (2 Master GP ports and 1 Slave - IP) configuration of the AXI interconnect.

however, the address editor GUI only shows the 0x4000_0000 to 0x7FFF_FFFF (1GB) address that corresponds to M_AXI_GP0.

I do not see the 0x8000_0000 to 0xBFFF_FFFF address space corresponding to M_AXI_GP1.

Is this expected behavior?


This issue has been fixed in Vivado Design Suite 2013.3 and later.
