4.1i XST - "ERROR:Xst:427 - Invalid file extension (.path\path\etc) for output format ngc"

Description

Keywords: path, command, line, extension, XST

Urgency: Standard

General Description:
When I specify the output file name in XST command line mode (-ofn), XST issues the following error message:

"ERROR:Xst:427 - Invalid file extension (.path\path\etc) for output format ngc."

Solution

XST will issue this error if a period exists in the path. To avoid it, simply remove any periods that are present in the output file name path.

(NOTE: This problem does not manifest itself in ISE, as ISE does not specify a path for the output file name.)

This problem was fixed in the 5.1i software release.
