4.1i XST - A "Memory Full" error is reported during low-level synthesis

Description

Keywords: XST, memory, full, generate, loop, 3.1i

Urgency: Standard

General Description:
When I perform low-level synthesis for a very large design with XST, memory usage becomes very high, but does not reach system limits. However, a "'Memory Full" error is reported, and synthesis stops.

Solution

Constructs for loops and generate statements can potentially use a great deal of memory. Breaking these constructs down into smaller loops may relieve the problem.

Many memory issues were resolved in the 5.1i version of XST.
