Any leading wdata signal is registered and held until the awaddr signal arrives. These signals are
described in A.5 ACE-Lite interface signals on page 254.
•
The MSI-64 Encapsulator requires a data bus that has a width of 64 bits or
greater.
•
The ACE-Lite manager port never issues more than two addresses before the
wlast signal asserts.
3.4.2 MSI-64 Encapsulator configuration
The MSI-64 Encapsulator does not have any configurable parameters at design time. However, if
this block is generated in your RTL design, it has several options that you can configure at build
time.
The MSI-64 Encapsulator is generated as part of any GIC configuration that includes an MSI-64
enabled ITS.
The following table shows the options for the MSI-64 Encapsulator that you can configure at build
time.
