- Interface to Configure
- This drop-down list contains the names of all the interfaces in the core. Select the interface you want to configure.
- Interface Name
- This option contains the name of the selected interface. You can change the text
in this box to change the name of the interface. The name must satisfy the
following rules:
- Contains only letters, numbers or "_" (underscore).
- Does not start or end with "_" (underscore).
- Does not contain "__" (double underscore).
Note: The name change only takes effect when you click another control in the customization page. - Interface VLNV
- Select the interface vendor, library, name, and version (VLNV) definition to use for this interface. Selecting undef lets you define the interface signals directly.
- Protocol Overlay to Apply to the VLNV
- Select the protocol to apply to this VLNV. Protocols apply some restrictions, such as presence and width, to some of the signals in the interface. This is only enabled for AXI4-MM interfaces and is only required to enable the Vivado IP integrator to connect the AXI-MM interfaces correctly.
- Interface Mode at Reconfigurable Partition
- Select the mode of the interface (master or slave) at the reconfigurable partition boundary.
- CDC Stages
- The number of synchronization stages to use when crossing between clock domains. Valid values are 0, 2, 3, 4, 5, 6.
- Add registers to interface
- Enables or disables registers on the interface to improve timing. Not all VLNVs will function correctly with this option enabled, so read the Registered Interfaces section carefully before enabling this.
