Synthesis crashes after synthesizing top level module

When synthesizing our project in vivado 2016.4, the synthetization crashes when it is done with the top-level module:

 

INFO: [Synth 8-256] done synthesizing module 'top-level module'
Abnormal program termination (11)

In version 2014.2 it works without problem.

I also tried in a fresh install of Ubuntu 16.04 virtual machine and the problem still persists.

 

I will include the error log:

#
# An unexpected error has occurred (11)

Stack:
/lib/x86_64-linux-gnu/libc.so.6(+0x354b0) [0x7f9b73c114b0]

Re: Synthesis crashes after synthesizing top level module

Hi @cpeppenster

 

The crash looks to me  design specific. Can you try synthesizing any example project to check and confirm if the issue is still there or not? Also will it be possible for you to share your design?

Rohit

Re: Synthesis crashes after synthesizing top level module

I found the problem. We tried to set attribute keep of a alias to an inout signal to true. When we removed this the design synthesized without crash.
