Synthesis

[spauly]

I am running ISE Project navigator version 11.2.  I can synthesize my design, but I get an error everytime I try to run Check Syntax on it.  The message it gives me is:

Started : "Check Syntax for 00723_370_00_top".
ERROR:Xst:2463 - File not found : "00723_370_00_top.lso".

Process "Check Syntax" failed

I have used many previous versions of ISE with no problems...this is the first time I have seen this issue.

Thanks for any help!

In the synthesis options dialog, there is an option for "use library search order file" or some such, as well as a way to set that file name. In previous versions if the "use search order" box was checked but no file existed, it would ignore the check. I guess 11.2 wants to honor the checkbox even if there's no file. Uncheck the "use library search order" box.

The "Use Synthesis Constraints File" checkbox was checked within the Synthesis Options dialog.  I unchecked this checkbox, but the Check Syntax still came up with the same error.  I do not believe this resolved the issue, but thank you for your help.

I think I found the issue.  The Design Properties dialog for the project has a Location field which is a subfolder of the Working Directory field.  All of my HDL sources are in the subdirectory provided by the Location field and the .LSO file mentioned in the error is also located in this Location subfolder.  I copied the .LSO file into the Working Directory folder and now Check Syntax performs properly without an error.   I may have specified a different working directory when beginning this project.  I would have hoped the ISE would have put the .LSO into the folder specified as my Working Directory, but it did not.  I can use this as a work around and I may try starting this as a new project to see if I can specify the same folder for both the Location and the Working Directory.
