1.9. Resource Utilization

Because the PCIe protocol stack is implemented in hardened logic, it uses no core device resources (no ALMs and no embedded memory).

The Avalon-MM with DMA V-Series variants include an Avalon-MM DMA bridge implemented in soft logic that operates as a front end to the hardened protocol stack. The following table shows the typical expected device resource utilization for selected configurations using the current version of the Quartus® Prime software targeting an V-Series device. With the exception of M20K memory blocks, the numbers of ALMs and logic registers are rounded up to the nearest 50.

Note: Soft calibration of the transceiver module requires additional logic. The amount of logic required depends upon the configuration.
