I am attempting a DC IR analysis using Ansys SIwave where I have multiple stages of resistors. Therefore, I have created a simple PCB for evaluation purposes. In the circuit, I have a voltage source, multiple resistors in series until it reaches an LED. For simplicity terms, I have created a dumbed down version of the setup.

I have set the voltage source on R1 and the LED as a current source.

I am not able to simulate successfully the correct voltage levels across different the resistors.

I am attaching the set configurations and the obtained results.

Can someone kindly guide me on the proper way to set this up?

Kindly correct the set-up for correct results.
1. Your voltage source must be connected between VCC and GND (not NetR1_2). Both voltage and current source should have the same reference net.

2. Select the "negative" for the voltage source under "Node to ground".
