This document states that these macro are not supported for Spartan and Virtex families

The table of architecture supported shows CBDXXCLED.

Is there a mistake?

解决方案

This macro is supported in Virtex and Spartan architecture, the AND gates will be implemented in LUTs.

The title of the table is wrong. It should read CB16CLED and NOT CBD16CLED.
