12.4 Project Navigator - MAP -global_opt returns to default value after restarting Project Navigator

Description

I change the MAP -global_opt to "Speed" and implement my design. The option is being correctly used, however, after I close and re-open the project, this property remains "OFF" and I have to set it again.

Solution

This issue can occur for some Spartan-6 and Virtex-6 FPGA designs, but not all. The".xise" project file is not updated with the process property.

<property xil_pn:name="Global Optimization map" xil_pn:value="Off" xil_pn:valueState="default"/>

Even if implementation is complete with "-global_opt speed", the process status icon displays as "out of date" after restarting the ISE tools.

This issue is resolved in ISE Design Suite 13.1.
