ise mapping options limited

Hi- I have a project in which I imported an EDK instantiated processor core- and have a whole bunch of logic around it.

For my initial build- this all worked well. The processor core was all EDK generated (NGC files I think), and I used synplify to synthesize my system_stub and user logic.

For the final build- I had to switch to importing my user logic as an EDF file from Synplify because I used a embedded core which uses a library- and ise doesn't pass that information to Synplify properly (acccording to user app notes).

The problem is in the initial build- under mapping properties- I get a whole slew of options- "Perform Time driven packing and placement" down to other map line options. (Solaris version 6.2.03i) In the final build- I see a much smaller subset of these options- "Perform time driven packing and placement" is not one of them. I had to use this option to meet my timing.

Anybody have any clue as to why these options would be gone? The fact that I am using a EDF for most of my RTL (top is still VHDL structural code)- shouldn't make any difference in the back end I wouldn't think?! Any ideas appreciated....

If you're using ISE from the project Navigator, there is a switch in the preferences for advanced options. This would seem to be global, since normally the same user would always want the same interface regardless of project, however the setting is saved with the project. So when you create a new project you need to go back to: Edit --> Preferences --> Processes --> Advanced. This should bring up the remaining options.
