Spartan-3E was supported in 7.1i, but it is not supported in 7.1i Service Pack 1. Why?
The data in 7.1i is not corrected and was mistakenly enabled in the 7.1i release. This data should not be used as a power estimate for Spartan-3E.
XPower support for Spartan-3E will be enabled in 9.1i Service Pack 1.
