Does Precision support Spartan-3A DSP with ISE 10.1?
Synthesis of Spartan-3A DSP designs is not supported through Project Navigator / Precision integration in ISE 10.1. At the time, ISE 10.1sp3 was delivered, Precision had not yet added support for this device.
In Precision 2008a.14, support for the Spartan-3A DSP device family was added. Therefore, users with this version will be able to successfully synthesize Spartan-3A DSP designs using Precision standalone.
Precision synthesis of Spartan-3A DSP designs will be supported through Project Navigator in ISE 11.1.
