4.2i XST - The constraint (.cst) file is deleted in ISE during the "Delete Implementation Data" process


Keywords: XST, CST, ISE, Delete Implementation Data, constraint

Urgency: Standard

General Description:
When working with an XST project in ISE, I specify a constraint file (.cst) for XST synthesis. (This is selected under the Synthesis Options tab of "Synthesis Properties"). However, when I select Project -> Delete Implementation Data, this file is deleted. This occurs even when the .cst file has been added to the project.


To prevent this file from being deleted, move it to any directory but the project directory. Then, specify this file in its new location using "Synthesis Properties" as usual.
