How to perform post-simulation

[Tom888]

We design a digitial interface in our application, I have
simulated the synthezied file(include *.sdf), now I want to add the
routine delay to the simulation.But the lay-out guy give us
files( *.spi )like this:

**********************************************************************
.SUBCKT AN4D2 Z A1 A2 A3 A4
M1 Z U18_IN VSS VSS N L=.50U W=8.56U
M2 Z U18_IN VDD VDD P L=.50U W=17.12U
M3 U18_IN A2 VDD VDD P L=.50U W=3.14U
M4 U18_IN A1 VDD VDD P L=.50U W=3.14U
M5 U18_IN A3 VDD VDD P L=.50U W=3.14U
M6 U18_IN A4 VDD VDD P L=.50U W=3.14U
M7 U18_IN A1 U19_U1_SOURCE VSS N L=.50U W=4.62U
M8 U19_U1_SOURCE A2 U19_U2_SOURCE VSS N L=.50U
+ W=4.62U
M9 U19_U8_DRAIN A4 VSS VSS N L=.50U W=4.62U
M10 U19_U2_SOURCE A3 U19_U8_DRAIN VSS N L=.50U
+ W=4.62U

..ENDS AN4D2

it seems like a spice model, Now I want to use modelsim(or vcs)
to perform the simulation, can it be possible? or
How to conver the file format?

Many thanks!
