rfThresholdXing

rfThresholdXing(
[ ?result t_result ]
[ ?resultsDir t_resultsDirectory ]
)
=> o_waveform / nil

Description

Calculates the threshold crossing value according to the jitter event time from the results of pnoise or hbnoise sample (jitter) analysis.

Arguments

?result t_result	Name of the result of pnoise or hbnoise sample analysis.
?resultsDir t_resultsDirectory
	Path to the results directory where simulation results of pnoise or hbnoise sample analysis are saved.

Value Returned

o_waveform	Waveform of threshold crossing with a time range, and a marker on the waveform with the threshold value.
nil	Threshold crossing value cannot be calculated because the specified result name is not correct.

Examples

The following example opens simulation results of pnoise sample analysis stored in the results directory.

openResults("/servers/user/rfJitter/testcase/simulation/Lib/Cell/View/results/maestro/ExplorerRun.0/1/pss_pnoise_trannoise/psf")

=> "/servers/user/rfJitter/testcase/simulation/Lib/Cell/View/results/maestro/ExplorerRun.0/1/pss_pnoise_trannoise/psf"

The following example lists the results stored in the currently open results directory.

The following example creates a waveform object wave1 that represents the waveform of threshold crossing values plotted against a time range. The waveform is plotted from the pnoise_sample_pm0 result.

wave1=rfThresholdXing(?result "pnoise_sample_pm0")

=> srrWave:0x35d19050

The following example creates a Waveform window and returns its window ID.

win1=awvCreatePlotWindow()

=> window:3

The following example plots the waveform object wave1 in the Waveform window win1.

awvPlotWaveform(

    win1

    list(wave1)

    ?expr list("thresholdXing")

    ?color list("y6")

    ?index list(1)

    ?lineType list("line")

    ?lineStyle list("solid")

    ?lineThickness list("thick")

    ?showSymbols list(t)

    ?dataSymbol list("X")

    )

=> t

Note that the time is plotted on x axis and voltage is plotted on y axis. The marker on the waveform shows the time and threshold value.
