6.2i BitGen - Certain BitGen options may increase the Virtex-II/Virtex-II Pro bit file size

Description

General Description:

The Virtex-II and Virtex-II Pro bitstream size can vary according to certain bitstream options:

1. Device stepping level (Virtex-II only)

2. FreezeDCI

Solution

When the CONFIG_STEPPING constraint is set to '0' in the design, BitGen will generate a large bit stream. BitGen will also generate a large bit file if FreezeDCI is set to YES.
