Install - How can I increase user mode virtual address space on a Windows Vista machine


I see the following error even though I have 4 GByte of RAM; how do I allow the tools to use all the RAM I have available?

ERROR:Portability:3 - This Xilinx application has run out of memory or has
encountered a memory conflict. Current memory usage is 2088772 kb.


You have to increase the user-mode virtual address space using BCDEDIT command as follows:

BCDEDIT /set increaseuserva <Megabytes>

If you want to increase it to 3GB: BCDEDIT /set increaseuserva 3072.

For more information, refer to Microsoft webpage

For Windows XP machines, see (Xilinx Answer 14932)
