[ ?graphType t_graphType ]
[ ?graphModifier t_graphModifier ]
[ ?waveType g_waveType ]
)
=> t / nil

Description

Evaluates the specified expression and plots the resulting waveform.

Arguments

t_expression	Expression to be evaluated and plotted.
?plotStyle t_plotStyle
	Plotting style. Valid values are Append, Replace, New Window, and New Subwindow.
?graphType t_graphType
	Type of graph. Valid values are Default, Rectangular, Polar, Impedance, Admittance, Immittance, and RealvsImag.
?graphModifier t_graphModifier
	Y axis of rectangular graphs. Valid values are Magnitude, Phase, WPhase, Real, Imaginary, dB10, dB20.
?waveType g_waveType
	Specifies whether the signal is Y versus Y or not. Valid values are YvsY and nil.

Value Returned

t	Expression is evaluated and the resulting waveform is plotted successfully.
nil	Expression cannot be evaluated because of an error.

Examples

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

awvCreatePlotWindow()

=> window:3

The following example opens the results stored in the directory ampsim.raw. The tran-tran result in this directory contains the signals net35 and net10 that are used in the expression to be evaluated and plotted.

openResults("/servers/user/design/ampsim.raw")

=> "/servers/user/design/ampsim.raw"

The following example evaluates the specified expression and plots the resulting waveform in subwindow 1 of the Waveform window that you created using awvCreatePlotWindow.

awvPlotSimpleExpression("v(\"net35\" ?result \"tran-tran\")-v(\"net10\" ?result \"tran-tran\")" ?plotStyle "Append" ?graphType "" ?graphModifier "Magnitude")

=> t

The following example opens the results stored in the directory prbs.raw. The tran-tran result in this directory contain a signal jitter that is used in the expression to be evaluated and plotted.

openResults("/servers/user/design/prbs.raw")

=> "/servers/user/design/prbs.raw"

The following example evaluates the specified expression and plots the resulting eye diagram waveform in subwindow 2 of the Waveform window that you created using awvCreatePlotWindow.

awvPlotSimpleExpression("eyeDiagram(v(\"jitter\" ?result \"tran-tran\" ?resultsDir \"./prbs.raw\") 200n 400u 2*40n   ?autoCenter t )" ?plotStyle "New SubWindow" ?graphModifier "Magnitude")

=> t
