AR# 10946

3.1i MAP - ERROR: "MapLib:102 - BUFG symbol...driving CLKDLL must be driven by CLKDLL too."

説明

Keywords: DLL, CLKDLL, BUFG, ERROR:MapLib:102 , must be driven, XIL_MAP_ALLOW_ANY_DLL_INPUT

Urgency: Standard

General Description:
In the 3.1i release, the XIL_MAP_ALLOW_ANY_DLL_INPUT environment variable allows input to the clock pin of a DLL to be from sources other than IPAD, IBUFG and BUFG. Some configurations fail with the error message:

ERROR:MapLib:102 - BUFG symbol "VCXO_divider_buffer" (output
signal=VCXO_clk_78) driving CLKDLL must be driven by CLKDLL too.

ソリューション

The scope of the variable is being changed to include these cases.

This problem is fixed in the latest 3.1i Service Pack, available at:
http://support.xilinx.com/support/techsup/sw_updates.
The first service pack containing the fix is 3.1i Service Pack 8.
