-- Description :
----------------------------------------------------------------------
-- the test checks the correctness of the two currents associated
-- as through between same terminals.for eg: consider 2 resistors in
-- parallel.. here vd is same and id and ic are the currents.
-- the test checks for the simpel diode implementation
-- wherein the charge is evaluated wrt a relative tolerance value
