Spartan-3E - Design tool requirements for production stepping silicon

Description

How do I target a Spartan-3E production stepping device in the ISE design tools?

Solution

No special input to the design tools is necessary to target stepping Spartan-3E parts. The CONFIG STEPPING constraint does not need to be set. The only design tool requirement is that production applications must be implemented using production speed files. For more information on the status of production speed files, see (Xilinx Answer 22037). No special software settings are needed to target production stepping devices. Consequently, you must be aware of the limitations of Stepping 0 silicon. For more information on stepping specifications, see the Spartan-3E Data Sheet located at:
