    when running a simulation MUST the IC circuit have a ground (ex, independent current source, no ground) Reply

    I am using a simple IC circuit with no Voltage source just a dependent current source and 5 resistors, but I cannot get the simulator to show the Voltage, Current, and Power of each element(resistor) inside the IC circuit...I believe it is because there is no ground in the Circuit...(see the Options File for the Circuit)

    The session log gave me

    You need to have at least one  reference node "0" in your circuit. You may want to make N00506 node as 0 or connect a very high value resistance say 100Meg between any node in your circuit and "0".
