AR# 41831: 13.4/14.7 MAP - "ERROR:Xst:3205" occurs when design contains a HARD MACRO with -global_opt enabled.
13.4/14.7 MAP - "ERROR:Xst:3205" occurs when design contains a HARD MACRO with -global_opt enabled.
During MAP the following error is reported:
ERROR:Xst:3205 - The block <sysClkStu1Inv_u> of type <inverter> is a HARD MACRO. Such cases are not supported by the Map -global_opt flow. You can rerun NgdBuild and set the environment variable XIL_NGDBUILD_BYPASS_ANNO to avoid this error. ERROR:Map:128 - Unable to run global optimization for this design. Please rerun Map with global optimization disabled.
The block sysClkStu1Inv_u is a hard macro, and -global_opt of map is enabled.
This restriction has been introduced in the 13.1 release of ISE Design Suite.
Two workarounds are available:
Turn off the "-global_opt" option.
Set the environment variable "XIL_NGDBUILD_BYPASS_ANNO" to 1.
