I have come up with convergency difficulty in hspice simulation with laplace_zp element.

It is an peaking amplifier and the simulation results looks good in AC simulation. However, in transient simulation it reports "internal time step too small".

Already tried method=gear option and still can't get it to work.

Please advice if you have better solutions.

If you are not using the 2009.03 release you should upgrade to it if possible. Also if you can post the circuit & va module we can take a look.
