Obj = SParameterChannel( 'FileName', 'default.s4p'. You create an SParameterChannel object by launching the sParamterFitter app from the base workspace. Note: defaults are provided for all settings if no entries are made when calling SParameterChannel.
The victim line is S31, the same-source crosstalk aggressor is S41 and the same-load crosstalk aggressor is S32.ĪutoDetectPortOrder - Boolean option to force auto-detect of port order. Consider the following 4-port single-ended system: While the same load definition is more direct, the same source definition is used by methodologies that rely on time domain excitation (like HSPICE) to stimulate the system with a single pulse or step response. For 'same-source' the stimulus is applied to victim input and probed at aggressor output and for 'same-load' (default) the stimulus is applied to each aggressor input and probed at the victim output. Signalling - Specify signaling as 'single-ended' or 'differential'.ĪggressorDefinition - Method of acquiring aggressor behavior. RxC - Single-ended capacitance value in Farads of the Rx structure. RxR - Single-ended resistance value in Ohms of the analog RX IO structure. TxRTFactor - The conversion factor from 20-80% or 10-90% to 0-100% risetime, default is 20-80%. TxRiseTime - The 20-80% rise time of the Tx stimulus waveform. TxAmplitude - Stimulus amplitude of the Tx output rising waveform. TxC - Capacitance value in Farads of the analog TX IO structure.
TxR - Single-ended impedance value in Ohms of the analog TX IO structure. StopTime - Desired duration of the Impulse Response in units of seconds. SampleInterval - Sample interval in units of seconds. MaxNumberOfPoles - Maximum number of poles to use for a fit output by the rational function.ĮrrorTolerance - Desired error tolerance in dB for a fit output by the rational function. PortOrder - Port order for the S-Parameter. FileName - Filename of the S-Parameter to be imported.
