DC convergence longer than transient/ ramping source

Question asked by R13801 on Apr 2, 2010
Im running ADS through RFIC dynamic link, on a quite complex BiCmos circuit.

I have observed that a DC analysis takes 1500sec ( 20000 iterations)  when the same analysis in transient where I am ramping the supplies with a PWL source ( on 1msec) is taking 100sec .  15times faster !!

Has anybody experienced this type of behavior ?

Any clue on the DC convergence parameters which could improve the convergence time ?
