General Description:
Version 2.1 of the Spartan-3 IBIS file generated by IBISWriter contains models for several SSTL and HSTL DCI inputs. When simulated in a standard environment, these models show unexpected results.
The following models are faulty and should not be used; they have been removed from 6.2is3 IBISWriter:
HSTL_I_15_DCI
HSTL_I_18_DCI
HSTL_III_18__DCI
SSTL18_I_DCI
SSTL2_I_DCI
Corrected versions of these models will appear in the IBIS files on the web as soon as they are available. Please note that models generated by IBISWriter are not always the latest available.
