5.1i XST - XST generates incorrect logic when dynamic shift register LUTs (SRLs) are inferred

Description

Keywords: Virtex

Urgency: Standard

General Description:
In 5.1i XST, dynamic SRLs may be inferred. For more information, see the XST User Guide at:
http://support.xilinx.com/support/sw_manuals/xilinx5/.

However, if the multiply (*) or divide (/) operators are used to determine the length of the SRL, XST will generate incorrect logic.

Solution

Currently, there is no known way to work around this problem.
