*Obsolete* 4.1i BitGen - The warning "INFO:DesignRules:548..." should be issued only when DSS_MODE is not "NONE", but it appears even when DSS is not used

Description

Keywords: DRC, BitGen, DSS_MODE, DSS_EN

Urgency: Standard

General Description:
The following warning should be issued only when DSS_MODE is not "NONE". However, this warning is currently reported whenever the DCM is used at all:

"INFO:DesignRules:548 - Blockcheck: The DSS feature of the DCM clk_rst_startup/clk_dcm_inst1 has limited EMI reduction capability. For maximum EMI reduction, an IP core available from Xilinx is recommended."

Solution

This problem is fixed in the latest 4.1i Service Pack, available at:
http://support.xilinx.com/support/techsup/sw_updates.
The first service pack containing the fix is 4.1i Service Pack 3.
