Production Stepping
The Spartan-3E FPGA family uses production stepping to
indicate improved capabilities or enhanced features.
Stepping 1 is, by definition, a functional superset of Step-
ping 0. Furthermore, configuration bitstreams generated for
Stepping 0 are compatible with Stepping 1.
Designs operating on the Stepping 0 devices perform simi-
larly on a Stepping 1 device.
Table 71: Differences between Spartan-3E Production Stepping Levels
Ordering a Later Stepping
-5C and -4I devices, and -4C devices (with date codes 0901
(2009) and later) always support the Stepping 1 feature set
independent of the stepping code. Optionally, to order only
Stepping 1 for the -4C devices, append an “S1” suffix to the
standard ordering code, where ‘1’ is the stepping number,
as indicated in
