Protocol validation occurs at the physical, data link, and transaction layers. In addition to the mandatory protocol compliance tests, the PCI-SIG® recommends more than a hundred additional tests to characterize PCIe designs accurately. Some of the most troubling PCIe issues occur during the bring-up sequence, where link partners fail to negotiate to the highest mutually supported speed, have high bit error rates, or operate in degraded modes. As a result, link training and status state machine (LTSSM) is crucial during protocol testing to ensure data packets transfer reliably between link partners.
PCIe protocol testing setup requires a protocol analyzer and exerciser. A protocol exerciser emulates both PCIe root complex and endpoint devices. The protocol analyzer acquires, records, decodes, and analyzes complex data from the physical layer all through the transactional layer. Combining the two instruments enables developers to create robust test cases and to quickly debug any detected errors in their PCIe devices.
How to Perform PCIe® 5.0 Protocol Validation
The Keysight P5552A PCIe 5.0 Protocol Analyzer introduces a new form factor that is easily deployable in the lab bench environment to enable deep protocol analysis of a PCIe system with unparallel signal integrity. Locate protocol errors or validate device operations by viewing data from the physical layer all through the transactional layer with ease.
