Spartan-7 FPGAs Data Sheet: DC and AC Switching Characteristics
DS189 (v1.2) June 20, 2017 www.xilinx.com
Preliminary Product Specification 12
Speed Grade Designations
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 Spartan-7 device on a per speed grade basis.
Production Silicon and Software Status
In some cases, a particular family member (and speed grade) is released to production before a speed
specification is released with the correct label (Advance, Preliminary, Production). Any labeling
discrepancies are corrected in subsequent speed specification releases.
Table 14 lists the production released Spartan-7 device, speed grade, and the minimum corresponding
supported speed specification version and software revisions. The software and speed specifications
listed are the minimum releases required for production. All subsequent releases of software and speed
specifications are valid.
