Hi,

Could you allow component parameters to be references to other component parameters? For example, when running a DC sweep, I'd like to observe outputs for a range of resistor values. However, there are two resistors in the circuit and the pair should be matched. A less trivial example would be testing a circuit's sensitivity (or lack thereof) to transistor beta when using a matched pair.

Thank you!

Hi Greg,

A component's parameter can't reference another component's parameter (for example, if R2.R was set to "R1.R"). However, you can achieve the same end goal by creating a global parameter (use the "Parameter Element" in the toolbox), and setting both R1.R and R2.R to the name.

See this example:

The value "R" of both resistors R1 and R2 could be just set to "Rdiv" to achieve the effect you're looking for!

Very nice! Thanks!
