1 Release Notes SnpExpert Release Notes

2 1. OVERVIEW Xpeedic SnpExpert provides a quick way to understand the electrical characteristics of the passive interconnectors in a system by not only viewing the S-parameter in frequency domain but also examining the time domain reflectometry (TDR). Oneclick definition of differential pairs and victim/aggressor setup, together with the built-in NEXT, FEXT, PSXT, ILD, ICR, and ICN, allows user to quickly evaluate the crosstalk. The Release Notes cover the following releases: SnpExpert Release Date: April 28, 2018 SnpExpert h1 Release Date: June 01, 2018 SnpExpert h2 Release Date: July 15, 2018 SnpExpert h3 Release Date: Aug 20, 2018 The Release Notes present the latest information about SnpExpert Version in the following sections: Supported Operation Systems New Features and Enhancements in SnpExpert New Features and Enhancements in SnpExpert h1 2 / 6

3 New Features and Enhancements in SnpExpert h2 New Features and Enhancements in SnpExpert h3 2. SUPPORTED OPERATION SYSTEMS SnpExpert is available on 64bit Window and Linux. Obtain the appropriate binary executable files for your operation system. The supported platforms for this release includes: Windows 7 SP1 Windows 8 Windows NEW FEATURES AND ENHANCEMENTS IN SNPEXPERT SnpExpert provides new features and enhancements as described in the Support Python script to invoke most SnpExpert features, including S- parameter import, plot, add mark, TDR, TOD and so on. Support CTLE and DFE adaptive optimization and manual tuning features when plot eye diagram, also provide real time equalization preview plot to ease the tuning process. Add new built-in compliances for S-parameter exploration, including OIF CEI_56G_LR_PAM4, OIF CEI_28G_VSR, IEEE 802.3cd, SAS 3.0, IEEE 802.3bz and MIPI D-PHY compliances. 3 / 6

4 Support parallelized COM analysis for IEEE 802.3cd, IEEE 802.3bs and IEEE 802.3by based on the latest compliance requirements. Add Apply to Cable/TML option in TOD and halve S-parameter to improve long transmission line de-embedding accuracy and speed. Add Open-Thru De-embedding (OTD) method for on-chip de-embedding. Support both Simplified and Advanced S-parameter cascading to accommodate difference usage scenario. Support multiple data curves gating with only one click, and export the whole S-parameter after gating. Support FFT_Mag(), FFT_dB(), FFT_Imag() and FFT_Real() functions for time domain data sources. Support PhaseDelay() and PhaseDelayDiff() to calculate group delay of both single-ended and differential S-parameter. Support horizontal line when add markers to measure delay and skew value. Explicit output PASS/FAIL information for Channel and Template Plot based on compliance limit. Support global variable definition and recursive invoke to better reuse between different data sources. Add S, Y, Z and RF template quick plot panel in SnpExpert main window. Support both single-ended and differential NEXT/FEXT/THRU S-parameter export when split S-parameter file with large number of ports. Support S-parameter plot with odd number of differential pairs. Support opening SnpExpert project by double click. 4 / 6

5 Save project status and user settings when software encounter abnormal situation. 4. NEW FEATURES AND ENHANCEMENTS IN SNPEXPERT H1 SnpExpert h1 provides new features and enhancements as described in the Improving the import speed of s parameters substantially. Update COM analysis for IEEE 802.3cd to the latest compliance requirement. Add "Apply to Cable/TML" in Dk/Df Extraction flow. Optimize the clarity of the exported pictures. Support to import parameters of single point frequency. Support to define the location of legend by "General Options". 5. NEW FEATURES AND ENHANCEMENTS IN SNPEXPERT H2 SnpExpert h2 provides new features and enhancements as described in the Add new built-in complainces for s-parameter exploration, including 802.3bj 100BASE CR4 MTF,802.3bs C2C_120D,802.3bs C2M_120E complainces. Update COM analysis for IEEE 802.3bs C2C_d2p1_120d to the latest compliance requirement. Optimize TDR algorithm to improve the accuracy,especially in the case of large oscillation. Add F,uF,nF,pF,fF and af etc units for capacitor. Support to modify the y-axis label and legend names. 5 / 6

6 Add an option to save a project with a link to all s-parameter files instead of duplicating them under a project in "General Options". 6. NEW FEATURES AND ENHANCEMENTS IN SNPEXPERT H3 SnpExpert h3 provides new features and enhancements as described in the Optimize TOD algorithm to improve de-embedding accuracy and calculation speed. Support double coordinate system to plot TDR. 6 / 6
