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 ?
thx
