An example of how to use the CCCS and CCVS elements.

Simulate > Time Domain > Run Time-Domain Simulation

thanks. it was useful

For the CCCS, How does the program translate the R1.nA. I know that R1 refers to the Resistor #1 but I do not understand the .nA part. I was thinking it referred to the node but in a circuit I was building When I ran a DC Simulation it failed due to an Undefined error. When I change the .nC to .nA or .nB it runs but it gives me 2 set of different values.

.nA is one end of the resistor and .nB is the other.

That's why if you change it to .nC for a 2 leaded component it throws an error.

It's a while since I've used these elements: I think the end (nA or nB) determines the direction of the current into the CCCS and CCVS parts. Easy enough to check.

Hover the mouse over the component pin ends so that the grey blob appears then look down in the bottom right hand corner of the editor screen. That shows you the pin names.

Cool! After doing Nodal Analysis on paper and comparing the results I found the answer to my problem thanks to your help. What the CCCS interpret .nA to be is the current running trough R1. .nB causes it to take the current running trough R1 but on the opposite side. So essentially which pin do you want to take the current of. :)) Thank you!
