AR# 12239: 4.1i XST - XST reports an error on the second run of a synthesis
4.1i XST - XST reports an error on the second run of a synthesis
Keywords: XST, dump, work, directory
General Description: When I perform an initial synthesis run in XST, no errors are reported. However, when I perform a second synthesis run, XST reports errors, even though nothing has changed in the design.
The problem lies with the "dump" directory. (The "dump" directory is the directory named "xst" in the project directory.) This directory contains the synthesis results of the libraries that are in the project.
Deleting the "xst" directory will resolve this problem.
Note: This problem has been fixed with the release of the 4.2i version of XST.
