AR# 32052

Description

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.
