Hi,

ISE 14.7, Win 7, 4GB(3.5 usable)
I have the following message when I try to simulate a project from command line. Surely, the project needs quite a lot of memory but I am worried that increasing the memory might make my system unstable. I wanted to hear if anyone has done it before and any recommendation.
ERROR:portability:3 - This Xilinx application has run out of memory or has
encountered a memory conflict. Current memory usage is 2042172 kb. You can
try increasing your system's physical or virtual memory. If you are using a
Win32 system, you can increase your application memory from 2GB to 3GB using
the /3G switch in your boot.ini file. For more information on this, please
refer to Xilinx Answer Record #14932. For technical support on this issue,
please visit https://www.xilinx.com/support.

Thanks!
 

For Win 7 buy more memory it can handle a lot more than just 4GB. I don't believe you can use /3G switch that was for 32-bit XP machines.

Here are the memory recommendations for various parts.

Just realized maybe you have the 32-bit version of Win 7. If so then if the PC hardware supports a 64-bit OS then install one. If you don't want to buy WIn7 64-bit, then buy memory, add another partition on your HD and install a 64-bit version of linux and get ISE for that OS.
 
All the solutions are costly. :) Thank you for the reply, I will see which one I will choose.
 

Plugging in 8 or 16 Gb doesn't seem all that costly... Certainly cheaper than waiting for ages while windows does the memory management dance, or running out of memory entirely. That said, I recently checked DDR2 SODIMM prices and those were a bit silly. So I should be more precise and say "Plugging in 8 or 16 Gb of mainstream DDR3 doesn't seem all that costly".
 

Well I think cost wise your best approach will be to upgrade the memory https://www.crucial.com/ and install 64-bit linux. You can install the Linux version of ISE without having to have a new license as the machine's NIC doesn't change (in case you thought you needed to purchase a new copy).
