Description
The Northwest Logic x1, x4, x8 PCI Express core provides a flexible, high-performance, easy-to-use local interface to the PCI Express bus. The core implements all three layers defined by the PCI Express standard and supports all key PCI Express features, including multiple virtual channels and traffic classes.

The core provides:

A control interface with consistent timing and function over all modes of operation
A data interface that connects directly to first-in-first-out (FIFO) interfaces
Separate clock domain transfers performed by the core for each virtual channel
Complete error-handling support
Push-button place-and-route timing with minimal routing constraints
The core is provided with a comprehensive verification suite with complete scripting and random stimulus capabilities that allow you to fully validate your design prior to use in hardware. The core has been extensively verified through ASIC-level testing methodologies and has been integrated in a wide variety of applications.

Also available from Northwest Logic are PCI Express development boards that you can use to quickly prototype a complete PCI Express system. A demo GUI, drivers, and an FPGA reference design are provided with the board.

Northwest Logic also provides customization and integration services to produce complete logic designs or sub-systems."
