11.3 XST - Running out of memory on a design that compiles successfully in previous versions

Description

Keywords: Portability, memory, limitation

I have a design that synthesizes successfully in previous versions of ISE 11 software. However, I encounter the following error in 11.3:

"ERROR:Portability:3 - This Xilinx application has run out of memory or has encountered a memory conflict. Current memory usage is 2082220 kb."

How can I resolve this error?

Solution

This is a known issue in ISE 11 software update 3 (11.3) that has been fixed in software update 4 (11.4).
