The INI strategy plays a crucial role in determining ownership for boundary NoC paths, which are paths that traverse the DFX boundary. Following are the configurable options for the INI strategy:

  • Single load, Driver owns the path
  • Single driver, Load owns the path

For boundary NoC paths that include an NMU located in the static region, the INI strategy must be set to Single load, Driver owns the path. This strategy ensures that the static region retains ownership of the path. To enable 1:N connectivity, you might need to incorporate multiple INI interfaces to connect to the NMU, as described in the next section.

Similarly, for boundary NoC paths where the NMU resides in the dynamic region, you have the flexibility to determine ownership as either the static or dynamic region. Selecting static region ownership requires configuring the INI strategy as Single driver, Load owns the path. Conversely, selecting dynamic region ownership requires configuring the INI strategy as Single load, Driver owns the path, as described in the next section.
