Different Results between Unix Cadence 4.46 and Linux Cadenc

Hi All,

I encountered something frustrated. I am using both Unix Cadece 4.46 and
Linux
Cadence 5.032. Even for the same design kit, I found that the results given
by them
are different! I found that there are about 1~2 dB difference in
S-parameters simulation.
Also, the curve shift! Have anyone experienced the same problem?

Ntfs:
We did see different noise results between 446 and 50. It turned out
to be the addition of the wdexp and ldexp resistor parameters. When
we set them to 1 we get the same results in 50 as 446.
