7.1i Timing/MAP - "FATAL_ERROR:Timing:bastwoffsetpref.c:585:1.93.2.5" occurs when I use the -timing switch

描述

General Description:

When I run MAP using the -timing switch, the following error message is reported:

"FATAL_ERROR:Timing:bastwoffsetpref.c:585:1.93.2.5 - Clock arrival time not found! Process will terminate. To resolve this error, please consult the Answers Database and other online resources at http://support.xilinx.com.

解决方案

This error occurs because a TIG is present on the clock path. As the timing tools do not have any information about the clock, an analysis cannot be run, which causes the error.

To avoid this problem, instead of using TIGs on clock paths to remove them from the unconstrained path report, use values (i.e., FROM:TO 10ns).
