An error about quartus_map.exe

[Altera_Forum]

Hi, 

 When compiling a design ,I encouter an error : Out of memory in module quartus_map.exe(2127 megabytes used).  Does it mean the memory of my computer is not enough for quartus to fulfill the compilation?   Thanks !

Yes your design is too large for the amount of RAM you have. 

 On 32-bit windows, I think processes are limited to about 2GB of memory even if the computer has 4GB. The only way to use more memory is therefore to get 64-bit windows.

According to Quartus readme.txt, designs for all Altera FPGA devices, except for Stratix IV can be handled with 4 GB memory and 32-Bit Windows.

See http://www.altera.com/support/software/quartus2/memory/qts-memory.html?gsa_pos=2&wt.oss_r=1&wt.oss=memory%2064-bit. 

 If you have 32-bit Windows and 3 GB of physical RAM, you can try the /3GB switch. See http://www.altera.com/support/kdb/solutions/rd11172005_572.html?gsa_pos=1&wt.oss_r=1&wt.oss=3gb. Lots of people have trouble getting that to work though (Windows issue, not a Quartus issue).
