User manual TEKTRONIX DPOQPI DATASHEET

[. . . ] Intel® Quick Path Interconnect Test Automation Software DPOQPI Data Sheet Intel® Quick Path Interconnect, sometimes referred to as "QPI", is an Intel-proprietary processor-to-processor interface that will be central to multiprocessor architectures for the next several years. Version 1. 0 of QPI, running at 6. 4 GB/s, is already common in current-generation commercial products. [. . . ] The user interface is designed to be focused, easy to set up, and simple to use. Features & Benefits Channel Embedding and Fixture De-embedding Two Types of Equalizer: CTLE + DFE Configurable Clock Recovery Eye Diagrams for Performance Visualization Histogram Accumulation and Export to an Intel-prescribed CSV File Format Automatic Test Termination at a Goal Population Remote Programmable Interface Data Sheet Intel® QPI V1. 1 Bus QPI V1. 1 is a point-to-point data communication bus with the following characteristics: Multilane architecture Unidirectional signaling Differential signal pairs (for both clock and data), DC coupled Forwarded clock for each link System reference clock (shared by Transmitter and Receiver at both ends of the link) Transmitter and Receiver equalization SSC capability PHY testing of this bus calls for some familiar measurements that are common to other high-speed serial buses, such as jitter, eye height, eye width, etc. Many of these measurements can be found in the DPOJET application. We have added two new measurements to DPOJET specifically for QPI V1. 1, "Eye High" and "Eye Low" which use histograms to record the voltage levels for logic High and Low states. However, QPI V1. 1 PHY testing also requires the ability to embed S-parameters to model the transmit channel, the ability to de-embed test fixture effects, use of CTLE and/or DFE equalization, etc ­ all of which potentially add to the complexity of configuring the measurement setup. The DPOQPI software combines all of the key capabilities mentioned above ­ and others ­ into an application-specific package that provides all the needed functions and controls in one simplified user interface. The software also features data logging and a remote programmable interface command set, so test operation can be controlled from an external management program and test results can be exported in the desired format.
