ISE version: 11.4
O.S.: Window 7 32-bit
RAM: Installed 4GB (just 2.99GB usable due to 32-bit limitation)
It passed the generate netlist state, but when I generated bitstream, then I got these following error. I have rebooted and turned off all of the application (accept XPS). Also, I tried to increase the Virtual Memory. Please help me to solve this physical memory issue. Thank you very much in advance!
BTW, I don't have this issue before when I synthesized & PARed the small design (same machine and setup).

According to memory requirements, XC5VLX110T requires 1.7GB of peak memory usage. My system has 2GB of RAM and it satisfies memory requirements.
Still it is running out of memory, as far as i understand it is saying to increase RAM from 2GB to 3GB using /3G switch in boot.ini file. Does that means I have to increase my system RAM ??

if it is memeory concern then use 64 bit Machine, if this doesn't help then try from command line or different os.
still if it is not working the you have see the report and check for which section/part it taking time or consuming memory.
if you able to narrow down your issue, then might be you can resolve it.
also you can check from synthesis report that it consume around 2 gb or not,
plz post if you narrow down the issue.
