pvrfreq

pvrfreq(
s_analysis
t_pos
t_neg
x_resistance
[ x_freq ]
)
=> o_waveform / nil

Description

Returns the spectral power from voltage and current for a specified frequency list or at all frequencies.

Arguments

s_analysis	Name of the analysis. Default value is hb.
t_pos	Positive node or net from the schematic or from the Results Browser. You can also specify a voltage value for this argument.
t_neg	Negative node or net from the schematic or from the Results Browser. You can also specify a voltage value for this argument.
x_resistance	Value of the resistance. You can specify any integer or a floating-point number.
x_freq	Frequency for which you want to plot the results. It is an optional argument. You can specify any integer value. Default value is nil.

Value Returned

o_waveform	Returns the waveform representing the spectral power on specified frequency or at all frequencies with resistor and voltage on the positive and negative nodes.
nil	Spectral power cannot be calculated because of an error.

Examples

The following example opens simulation results of hb-hbnoise analysis stored in the specified results directory.

openResults("/servers/user/testcase/simulation/lib/cell/maestro/results/maestro/ExplorerRun.0/1/test/psf")

=> "/servers/user/testcase/simulation/lib/cell/maestro/results/maestro/ExplorerRun.0/1/test/psf"

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

results()

=>

(xf hb_fi hb_fd hb_td hbnoise_sample_hm0

    hbnoise_sample_hm1 model instance output designParamVals

    primitives subckts variables

)

The following example selects the result hb_fi.

selectResults('hb_fi)

=> stdobj@0x31533260

The following example lists the output signals stored in the selected result.

outputs()

=>

("/net3" "/emitter" "/net021" "/net17" "/varactor1"

    "/net30" "/collector" "/base" "/net8" "/out"

    "/IPRB0/PLUS" "/L0/PLUS" "/L1/PLUS" "/V0/PLUS" "/V1/PLUS"

    "/V2/PLUS"

)

The following example creates a waveform object wave that represents the spectral power calculated for the arguments specified for the function pvrfreq.

wave=pvrfreq("hb" "/net30" "/net021" 20 4e9)

=> srrWave:0x35729b00

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

win=awvCreatePlotWindow()

=> window:3

The following example plots the waveform represented by the waveform object wave.

awvPlotWaveform(

    win

    list(wave)

    ?expr list("spectralPower")

    ?color list("y6")

    ?lineType list("line")

    ?lineStyle list("dash")

    ?lineThickness list("thick")

    ?showSymbols list(t)

    ?dataSymbol list("o")

    )

=> t
