Hi, I am trying to confirm that two currents in my circuit sum up to 0. I
tried the following two approaches. 1. ".probe tran Itotal = par('I(vin1)
+ I(vin2)') " to view the total current from the two voltage sources. 2.
use the expression tool from awaves to compute the total current. I expect
they should give similar result and the first one should give more
accurate result since the second approach reads data from .tr0 file which
only contains data points specified by the time step. However, these two
gave me completely different results, several orders of magnitude
difference! Did I do something wrong? Thanks!
