*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


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."


This problem is fixed in the latest 4.1i Service Pack, available at:
The first service pack containing the fix is 4.1i Service Pack 3.
