Synthesis

[alexandre.solon]

Hi everyone,

I've been trying to synthesize a project in EDK 11.1, but I am getting a portability:3 error message:

XST: Portability:3 This Xilinx application has run out of memory or has encountered a memory conflict...

XST stops right at the 2GB barrier, but my machine has 4GB of memory. I think that this might be a Windows 32-bit Physical Address Extension error.

Or perhaps, EDK 11.1 is limiting XST to 2GB.

I have already read lots of comments in the forum, but none of them has helped yet.

Do I really have to buy a 64-bit machine?

How can I optimize my project in order to reduce XST work?

Does the update to 11.5 fixes this problem?

Thanks in advance,

Hi,

Windows allocates 2GB to user processes. You can set /3GB switch to enable 3GB - see this ms technet article 

Hope that helps,

I install 4GB DDR3 memory on my computer(Windows XP 32bit SP3), and I edit the boot.ini file by adding /3GB /USERVA=3000(according #14932), but when I synthsis my design again, the same error also ocurs.

How can I fix it?

Thanks

You need a 64-bit OS and more memory. That's how you fix it.
