Spectrum Software

 

News:

Spectrum Software has released Micro-Cap 9, the ninth generation of our SPICE circuit simulator.

For users of previous Micro-Cap versions, check out the new features available in the latest version. For those of you who are new to Micro-Cap, take our features tour to see what Micro-Cap has to offer.

 

 

Analysis - General

 

Is it possible to plot the voltage of a node that lies within a macro during the simulation
of the calling circuit?

 

All of the standard circuit variables within a macro or a subcircuit are available for
plotting during a simulation. To reference a node name or a part name of an object within a macro
or subcircuit, dot notation needs to be used as in the following format:

Subcircuit\Macro Part Name + "." + Node\Part Name

For example, to reference the voltage of node 6 in the macro X3, the following expression would
be used:

V(X3.6)

Similarly, the expression:

I(X6.R1)

would plot the current through the resistor R1 that is within the macro or subcircuit X6.

The dot notation may be used to plot circuit variables that are nested within multiple layers of
macros or subcircuits by concatenating the macro or subcircuit names. The expression:

V(X1.X2.X3.10)

would plot the voltage of node 10 in the X3 subcircuit, within the X2 subcircuit, within the X1
subcircuit.

The Variables list which is invoked by right clicking in a Y Expression field of the Analysis limits
displays a menu which shows all of the circuit variables available for plotting. Subcircuit and
macro variables will also be displayed in this list if they are present in the circuit.
