Plotting Internal Pin Values
Plotting Internal Pin Values
To measure the intrinsic value of a pin you use the same syntax as for measuring its extrinsic
value. However, you use an index number greater than the number of pins available that
corresponds to the pins position. For example, the source voltage pin is the third pin of a
MOSFET and there are four pins in total. Therefore, to obtain the intrinsic source voltage of this
MOSFET you would use:
.PLOT V(Mx.7)
To obtain the intrinsic value of the drain current pin of a JFET you would use:
.PLOT I(Jx.4)
Note
If the position number used is greater than the index available for the device it will return a
value of zero.

Complex Modifiers and Initial Formatting
Some results are real quantities, such as the currents and voltages from a transient analysis,
while others are complex. In this case, real or imaginary parts, magnitude or phase or group
delay, can be required by the user.
Use option ACOUT to control how complex expressions VX(a,b) and IX(a,b) are computed in
AC analysis for their decibel magnitude, magnitude, phase, and group delay values.
It is also possible to specify some initial basic formatting of the results. For example, spectral or
scattered display modes can be specified, instead of the default continuous-line mode. S, Y, Z
parameters can be automatically displayed in a Smith chart, and so on. These optional
specifications do not alter the raw data, they only tell the waveform viewer how to display the
data initially.
Tip
See “.OPTION ACOUT” in the Eldo Reference Manual.
