PCI Express Analysis Solutions
Teledyne LeCroy introduced their PCI Express Analyzer technology in the spring of 2003 for Gen1 applications. Since that time the protocol analyzer has become an essential tool in many industry leader’s labs that have successfully brought PCI Express based products to market. Working with these companies has helped produce the right user interface and analysis features for PCI Express Protocol debugging and performance enhancement.
Teledyne LeCroy offers three protocol analyzer product lines (Summit™ , PETracer™ ML, Edge T1-4). The Summit T2-16 Analyzer is Teledyne LeCroy’s fourth generation architecture and highest performance platform. It provides full bidirectional support of x16, x8, x4, x2, and x1 at data rates up to 5 GT/s.With 8 GB of trace memory, it offers enough capacity for analyzing and recording extensive PCI Express data streams. Supporting lane widths up to x4 at 2.5 GT/s, the PETracer ML Analyzer has 2 GB of trace memory and offers outstanding performance for Gen1 PCI Express applications. For portability and ease-of-use the Edge T1-4 Analyzer offers Gen1 analysis and low cost form factor for add-in-boards applications
Teledyne LeCroy's PCI Express Protocol Analyzer solutions employ high impedance, non-intrusive probing technology thereby allowing fully unaltered data pass-through. In addition, it leverages the intuitive and powerful Teledyne LeCroy Trace expert software system, embedding a deep understanding of the PCI Express protocol hierarchy and intricacies and presents this knowledge to the user in a colorful, intuitive and easy to use graphical display, allowing users to quickly capture and validate PCI Express product designs. These analyzers enable IP, semiconductor, switch, software and system developers as well as add-on card vendors to quickly identify protocol violations and ultimately reduce development and debugging time.
Developers can use Teledyne LeCroy's PCI Express Protocol solutions to easily capture and decode PCI Express Transaction Layer Packets (TLPs), Data Link Layer Packets (DLLPs), and low-level link traffic, including Training Sequences and Skip Ordered-sets. Some of the errors detected include: 8b/10b errors, such as invalid symbols and incorrect running disparity; CRC errors; idle data errors; and EDB (End-of-Packet Bad) errors. They also provide a detailed display of split transactions, correlating requests transmitted from one PCI Express endpoint with completions received from the endpoint at the opposite end of the link.
The PCI Express exercisers assist with generating PCI Express transactions, observing behavior, and performing both stress testing and compliance testing. The Summit Z2-16 supports the new Specification 2.0 (“Gen2”) data rates of 5 GT/s across up to 16 lanes. The PETrainer ML Exerciser supports up to x4 lane widths at data rates of 2.5 GT/s. As complete solutions, both the Summit T2-16 and Summit Z2-16, or PETracer/Trainer™ systems give you the unique ability to record (capture) live traffic, modify the traffic, and then playback the exact data stream, or “script,” using the exerciser.
Protocol Test Card
Teledyne LeCroy offers an integrated and automated compliance testing system, including the Protocol Test Card, approved by the PCI-SIG® as a standard tool for compliance testing for developers working with the new Gen2 specification.
PCI Express Physical Layer Testing
The Teledyne LeCroy SDA 6020 Analyzer and PCI Express Compliance and Development software offer a complete test and debug. QPHY-PCIe provides a highly automated solution for PCI Express 1.1.
The Teledyne LeCroy SDA 13000 can perform PCI Express 2.0 Compliance Test and Debug. It can acquire and quickly analyze PCI Express 2.0 signals using the SigTest(PCI-SIG Compliance Utility). The SDA 13000 has the memory depth to acquire all required 1 million UI in a single acquisition. Waveforms can be saved in the TRC format and quickly analyzed by SigTest. Built into the standard SDA tools are the 14 Masks, 3 PLLs and 2 Jitter Filters specified by PCI-SIG.
