I set an initial condition for a capacitor in its VALUE attribute as '10p IC=10', but when I run the analysis, I get -10V across the capacitor. Why?
The capacitor does have polarity, so this condition will place 10V across the capacitor in relation to its plus and minus pins. You can view which pin is which by enabling the Display Pin Names checkbox in the Attribute dialog box. If the polarity is reversed, just rotate the capacitor so that the plus pin and the minus pin are swapped, or you can just set the initial condition to -10V.
