[IBIS] [IBIS-Users] WARNING Endpoint

Hi  IBIS experts,

when I check  my  IBIS  model  I  optain  these warning:

WARNING - Model 'mod_out': TYP AC Rising Endpoints ( 0.00V,  4.97V) not 
within
          0.099V (2%) of ( 3.11V,  3.94V) on VI curves for 1000 Ohms to 0V
WARNING - Model 'mod_out': TYP AC Falling Endpoints ( 0.02V,  5.00V) not 
within
          0.100V (2%) of ( 3.14V,  3.96V) on VI curves for 1000 Ohms to 5V

I  know  what it means,  but  I  don't know if  I  have  to modify
the  R_fixture to  eliminate it ( I fix R_fix=1k from the datasheet ).
morever in some IBIS editor this  Warning became an Error !
so  I  don't know if is an acceptable Warning.
( I use s2ibis2 v.2.1 )

What  do you think about?

many  thanks


Another type of question:
About IBIS Summit ( DATE 06 ), there is an expiry date to register on them?

thanks again.

Fabio.
