Checked console message as well as transcript.
It looks simulation went through as expected, just don't see GUI, command prompt pops and disappears briefly.
ISE Console message:
INFO: Automatic do files created successfully. Launching ModelSim GUI ... Modelsim GUI launched successfully Process Simulate Behavioral Model setup completed successfully, the GUI will be up in a moment.
I could do simulation by manually starting vsim, and run the .fdo script.
Thanks for your attention,

Hope you are using Modelsim 10.2a and above with ISE 14.7 as they are the supported version.
Also check the modelsim status in Application section from Windows task manager.

Thanks for reply, I am dealing with ModelSim 10.4 SE. I can tell it ran by reading the script. Just GUI never pops up, command prompt flashes briefly. Don't see any ModelSim stuff in Windows Task Manager. But it ran, based on transcript.

Are you able to invoke modelsim GUI standalone?
02-09-2016 08:01 PM
Yes, I can run ModelSim standalone and do the *.fdo script without any issue.
Just not sure when ISE is used to call vsim, which modelsim.ini it uses. I have two, one in modelsim installation folder one in compiled library folder. But both have valid settings.
I will try new installation on a different machine when I have time.

It uses compiled library location modelsim.ini if you have set the compile library location correctly in simulation properties.
Otherwise, it will check present working directory or the location that was set to MODELSIM environmental variable (if set)

Same thing on another machine, not able to see GUI.
It seems ModelSim runs properly in script mode, but ISE can't bring up the GUI.

Did you try running simulation in modelsim when invoked in stanalone mode?

Can you try lauching Vivado from tcl shell and see if it helps?
Also, check if the path to simulator is provided properly.
