13.1 MAP - "FATAL_ERROR:1::78:1.3 - Physical Synthesis Failed"

Description

I am seeing the following MAP fatal error:

FATAL_ERROR:1::78:1.3 - Physical Synthesis Failed. Process will terminate. For technical support on this issue, please open a WebCase with this project attached at http://www.xilinx.com/support

/opt/Xilinx/13.1/ISE_DS/ISE//lib/lin64/libXst_Core.so: error: symbol lookup error: undefined symbol: _ZN5antlr6BitSetD1Ev

How do I fix this issue?

Solution

This issue is observed when register duplication is turned on, which causes Physical Synthesis to load the XST library. 


Turning off the register duplication option results in a successful implementation.


If turning off the register_duplication (or logic_opt) does not solve the issue, check the version of the glibc library installed on the machine (for example, glibc 2.5-58.el5_6.4. )

Rolling back to glibc 2.5-58.el5_6.3 resolves the issue. 

Note: packet glibc 2.5-58.el5_6.4 was distributed on 27.05.2011 and goes with several supported versions.


You can also work around this problem by setting the environment variable as follows:

setenv LD_PRELOAD /Xilinx/13.1/ISE_DS/ISE/lib/lin64/libAntlr.so (Correct path for your installation)
