AutoESL - Incorrect implementation for nested loop when "rewind" option is applied for pipeline directive
When an AP PIPELINE REWIND directive is applied on a nested loop, AutoESL incorrectly implements the function.
This issue is resolved in the 2012.1 version of AutoESL.
The rewind option works with a single loop or a single flattened nested loop.
Therefore, for nested loop, the rewind option should be applied only on the outer loop with all inner loops unrolled.
