[SI-LIST] Convergence problems with Hspice

Hi,

I am trying to run some spice simulations but running into problems.  What
  I have is three blocks, basically, a driver, the package model for the IC 
and
30 inches of trace (created using the W transmission line model).  When I
run the driver by itself it looks like it is supposed to.  Driver + package 
model
looks good.  Driver + transmission line model looks good, but when I put all
three together I run into all kinds of convergence problems.  The package 
models
were created using Ansoft Spicelink, the version of hspice that I am using 
to run
these simulations is 2001.2.  Has anybody seen similar errors trying to run
simulations which are similar to mine.

Thanks in advance,
Khalid
