laplace_zp

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.
