Virtex-II Platform FPGAs: DC and Switching Characteristics  
Virtex-II Switching Characteristics  
Switching characteristics in this document are specified on  
a per-speed-grade basis and can be designated as  
Advance, Preliminary, or Production. Note that Virtex-II Per-  
formance Characteristics, page 7 are subject to these  
guidelines as well. Each designation is defined as follows:  
Testing of Switching Characteristics  
All devices are 100% functionally tested. Internal timing  
parameters are derived from measuring internal test pat-  
terns. Listed below are representative values. For more  
specific, more precise, and worst-case guaranteed data,  
use the values reported by the Xilinx static timing analyzer  
and back-annotate to the simulation net list. Unless other-  
wise noted, values apply to all Virtex-II devices.  
Advance: These speed files are based on simulations only  
and are typically available soon after device design specifi-  
cations are frozen. Although speed grades with this desig-  
nation are considered relatively stable and conservative,  
some under-reporting might still occur.  
IOB Input Switching Characteristics  
Preliminary: These speed files are based on complete ES  
(engineering sample) silicon characterization. Devices and  
speed grades with this designation are intended to give a  
better indication of the expected performance of production  
silicon. The probability of under-reporting delays is greatly  
reduced as compared to Advance data.  
Input delays associated with the pad are specified for  
LVTTL levels. For other standards, adjust the delays with  
the values shown in IOB Input Switching Characteristics  
Standard Adjustments, page 11.  
Table 13: Virtex-II Device Speed Grade Designations  
Production: These speed files are released once enough  
production silicon of a particular device family member has  
been characterized to provide full correlation between  
speed files and devices over numerous production lots.  
There is no under-reporting of delays, and customers  
receive formal notification of any subsequent changes. Typ-  
ically, the slowest speed grades transition to Production  
before faster speed grades.

Since individual family members are produced at different  
times, the migration from one category to another depends  
completely on the status of the fabrication process for each  
device. Table 13 correlates the current status of each  
Virtex-II device with a corresponding speed grade designa-  
tion.
