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 does not support simulation on the Xcelium* simulator.
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 32-bit address PIO is not supported when both the 32-bit addressing and 32-bit PIO are enabled.
Note: The R-Tile MCDMA BAM + MCDMA design example generation fails when the 32-bit address routing is enabled.
Note: The R-Tile design example does not support PIPE mode simulations.
