5 Smart Tool Suite Description Smart Tool Suite is a software tool to help engineers perform various types of electromagnetic analysis very rapidly. Smart Tool Suite consists of a Graphical User Interface (GUI) and a number of kernels depending on the functions that are included. At this time, the available functions include: Plotting S/Z/Y-parameter files from Touchstone format or CSV format. Multiple curves can be included on a single plot, and the plot can be modified to change scales, line widths, grid format, and many other attributes. The plots can then be saved in PNG format for later inclusion into other documents and presentations. Causality and passivity (CaP) analysis on multiport S-parameter files. A visual indication whether each of the individual S-parameters are causal and/or passive is shown, as well as details on which portions (if any) are not causal or passive. The TDR/TDT tool provides functionality to calculate time domain responses for reflections as well as the through. The tool requires s-parameter blocks in Touchstone files as input. Any number of ports are supported. Calculations are based on a FFT algorithm. Smart Fixture De-embedding (SFD). SFD Extracts DUT from Fixture + DUT + Fixture structure. Tool requires S-Parameters for total structure and S-Parameters for Fixture. Fixture also can de loaded as a symmetric 2x structure Fixture + swapped(fixture). In this case, before de-embedding tool will extract 1x structure from the symmetric 2x structure. 5

42 Passivity Causality Tool: Description Description Causality and Passivity is an easy to use tool to check the passivity and causality of S-parameter files. Both measured results and simulation results can result in noncausal and/or non-passive data. Using such non-passive or non-casual data for signal integrity analysis can result in incorrect results. Any size S-parameter file can be used. Data is read directly from touchstone files, and the user can perform the analysis on any individual S-parameter or all S- parameters. A matrix of red/green indicators show if a particular S-parameter is causal and/or passive. Users can view the results for each S-parameter to see how badly a failing S-parameter fails the test. Enforce Causality and Passivity If an S-parameter file fails causality and/or passivity, users can select to force causality and then save the corrected file for use in further analysis. 42
