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.
