Switching characteristics are specified on a per-speed-grade basis and can be designated as Advance, Preliminary, or
Production. Each designation is defined as follows:
Advance Product Specification
These specifications are based on simulations only and are typically available soon after device design specifications are
frozen. Although speed grades with this designation are considered relatively stable and conservative, some under-reporting
might still occur.
Preliminary Product Specification
These specifications 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 Product Specification
These specifications are released once enough production silicon of a particular device family member has been
characterized to provide full correlation between specifications and devices over numerous production lots. There is no
under-reporting of delays, and customers receive formal notification of any subsequent changes. Typically, the slowest
speed grades transition to Production before faster speed grades.
Testing of AC Switching Characteristics
Internal timing parameters are derived from measuring internal test patterns. All AC switching characteristics are
representative of worst-case supply voltage and junction temperature conditions.
For more specific, more precise, and worst-case guaranteed data, use the values reported by the static timing analyzer and
back-annotate to the simulation net list. Unless otherwise noted, values apply to all Artix-7 FPGAs.
