Hi Everyone:

I have a question for all of you spice users of tranmission analysis and
PCB/signal integrity.

What method have you guys used for simulations? Do you prefer the Gear
Method or do you prefer the Trapezoidal method? There are some charge
conservation issues within the process spice model that can affect what
method is best used.
Can anyone comment on this for me and explain your reasons for using
either of the methods?
