The recent note that appeared describing a difference between the
version of SPICE 2g6 distributed by Berkeley and the version
distributed by us is indeed correct.  Some time ago we inadvertantly
introduced this bug into the calculation of narrow channel effects on 
threshhold voltage.

On line 1985 of file dctran2.f, the last variable used to calculate
FACTOR should be XL (not XW). The line should read:

  200 FACTOR=0.125D0*FNARRW*TWOPI*EPSSIL/COX*XL

What can I say....we goofed.  

We appreciate any and all feedback from users on the tools we
distribute and will inform everyone of serious problems.
