QPro 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. Each designation is
defined as follows:
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.
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.
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-
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,

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.
