12.4 Project Navigator - The "Retiming" option is not being saved in projects using Synplify_Pro


My ISE project originally had "-retiming" selected within the "Synplify_Pro" -> "Process Properties" under "Design Options" for running Synthesis, but after reopening the project within Project Navigator this box is no longer selected.


This is a known issue in all 12.x releases when working with an ISE project and Synplify Pro. To work around the issue, ensure you recheck the box prior to running synthesis after re-opening the design.

The issue is fixed in ISE 13.1 software.
