Note: R-Tile MCDMA IP PIO using Bypass Mode design example simulation is supported in x16 and x8 topologies.. The remaining R-Tile design example simulations are not supported.
Note: R-Tile MCDMA IP 4x4 design example does not support simulation.
Note: R-Tile MCDMA IP design example doesn’t support multiple physical functions and SR-IOV for simulation.
Note: Data Mover Only Mode is not available in R-Tile MCDMA IP x4 topology.
Note: For 2x8 Hard IP modes, simulation is supported on PCIe0 only.
Note: The R-Tile design example supports PIPE mode simulation, which is now the default mode of simulation.
