Description

Keywords: UtilCnameimp, maximum, name, Synplify, Certify

The following MAP error occurs when I run a design netlist generated by Synplicity.

"FATAL_ERROR:Utilities:UtilCnameimp.c:425:1.13 - maximum name length exceeded.
Process will terminate. For technical support on this issue, please open a

Solution

This is a known problem that occurs when using Synplicity's Certify 9.2 and Synplify Pro 9.6.2. Synplicity has provided a patch to resolve the problem. The 2048 character limit is considered to b a reasonable limit, so no change is scheduled for the Xilinx MAP application.
