PHY MAC, Data Link Layer, and Transaction Layer for PCIe interfaces. The PIPE
interface is used as the interface between the transceiver and the hard IP block.
Figure 1–42. PCI Express Hard IP High-Level Block Diagram
The hard IP block supports 1, 2, or 4 initial lane configurations with a maximum
payload of 256 bytes at Gen1 frequency. The application interface is 64 bits with a data
width of 16 bits per channel running at up to 125 MHz. As a hard macro and a verified
block, it uses very few FPGA resources, while significantly reducing design risk and
the time required to achieve timing closure. It is compliant with the PCI Express Base
Specification 1.1. You do not have to pay a licensing fee to use this module.
Configuring the hard IP block requires using the PCI Express Compiler.
For more information about the hard IP block, refer to the
Guide.
