IP Core Verification
To ensure compliance with the PCI Express specification, Altera performs extensive verification. The
simulation environment uses multiple testbenches that consist of industry-standard bus functional
models (BFMs) driving the PCI Express link interface. Altera performs the following tests in the
simulation environment:
• Directed and pseudorandom stimuli are applied to test the Application Layer interface, Configuration
Space, and all types and sizes of TLPs
• Error injection tests that inject errors in the link, TLPs, and Data Link Layer Packets (DLLPs), and
check for the proper responses
• PCI-SIG
®
Compliance Checklist tests that specifically test the items in the checklist
• Random tests that test a wide range of traffic patterns
Altera provides the following two example designs that you can leverage to test your PCBs and complete
compliance base board testing (CBB testing) at PCI-SIG.

Compatibility Testing Environment
Altera has performed significant hardware testing to ensure a reliable solution. In addition, Altera
internally tests every release with motherboards and PCI Express switches from a variety of manufac‐
turers. All PCI-SIG compliance tests are run with each IP core release.
Performance and Resource Utilization
Because the PCIe protocol stack is implemented in hardened logic, it uses less than 1% of device
resources.

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