TclStackFree: incorrect freePtr. Call out of sequence? in Vivado 2016.2

Jump to solution

Hi everyone,

 

I got this error when synthesised a specific design in Vivado 2016.2. Previously, other designs could be synthesised successfully.

 

I have read threads from the same issue on Vivado 2016.4 and this, and applied their suggestions, but my problem has not been resolved.

 

As I said before, I have faced this problem only in a specific design. Other designs have been working fine.

 

Attached is my synthesis runme.log file.

 

If you want to reproduce this issue, leave me a message, I can share my design via Dropbox.

 

Kind regards,

Khoa

Hi @khoa_pham, this issue does not occur with the latest version of the tools, 2018.2. Are you able to run the design through a newer version of the tools?

Usually this error is due to out of memory.

What operating system are you using?

It is better to provide your design to reproduce the issue for investigation.

Hi @viviany,

 

I thought about the run-out-of-memory issue, but after checked my machine consumed only ~30 GBs out of 64 GBs at that time. I also reduced the system memory by closing other programs and had Vivado re-run at ~15GBs. The problem still happens.

 

Moreover, I don't have any special character in my PC name or path, see the attached figure for my PC info.

 

My design is related to a running project, so I definitely share it if you drop me a private message.

 

Kind regards,

Khoa

Hi @peadard,

 

Thanks for your quick answer!

However, is there any solution/suggestion for Vivado 2016.2 as all of our project stacks (hardware designs + software drivers) are being built on 2016.2 version?

Porting to another version could be troublesome and take time and efforts so we will consider to do if it is a must.

 

Kind regards,

Khoa
