Solution

This message appears when there is an attempt to nest a block comment (which starts with /*) within another block comment in Verilog. This is in violation of Section 2.2 of the Verilog LRM.

WHAT NEXT:

Remove the nested block comment from the surrounding block comment, and re-run XST

EXAMPLE:

Consider the following RTL

/* Copyright 1971 ReallyOldCompany
/* Author: Foo Bar
* This RTL contains the top level module
* It instantiates all other submodules */
...

Clearly, line 2 of the above RTL is an attempt to nest a block comment within the larger block comment. Removing the line containing the start of the nested block comment, or changing the /* to * will solve the problem
