Re: [IBIS] Could IBIS model suport the invert buffer?

Hello bi, 

You can make use of "Polarity" keyword to support such options. 

"Polarity Non-Inverting" : for Buffers 
"Polarity Inverting" : for Inverters 
Moreover ther would be no changes in curves charateristics

for further information please refer to latest IBIS cookbook. 

WIth Best Regards
