7.1 MAP - "FATAL_ERROR:Pack:pkibatranslate.c:1592:"


General Description:

My design fails in MAP with the following fatal error. Why?

FATAL_ERROR:Pack:pkibatranslate.c:1592: - Frags within comp "146917" have differing parent blocks. One parent is "zmi4k_top" and another is "e2". Process will terminate. To resolve this error, please consult the Answers Database and other online resources at http://support.xilinx.com.If you need further assistance, please open a Webcase by clicking on the "WebCase" link at http://support.xilinx.com

This problem can occur if IO symbols that need to be packed into a single component belong to different hierarchies and the KEEP HIERARCHY option is enabled for MAP. Work around is to run MAP with "-ignore_keep_hierarchy" option.


This problem has been fixed in the latest 7.1i Service Pack available at:

The first service pack containing the fix is 7.1i Service Pack 3.
