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.

Solution

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 http://msdn.microsoft.com/en-us/library/aa906211.aspx
