Incompatible Format of Standard IEEE Library

Description

I received following error during compilation:

ELBREAD: Error: Library '<standard library>’ has incompatible format. Recompile all library units.

How do I fix it?

Solution

The error appears when the workspace/design created in older version of Active-HDL is opened in newer version of the tool. The library.cfg file located in the workspace folder contains an absolute path to the vendor libraries. Because the new version of the tool is used, this path is not valid anymore and the above error message is generated.

Please try the following:

1. Close workspace in Active-HDL.

2. Use Windows Explorer to locate the workspace folder.

3. Delete library.cfg file.

4. Open workspace in Active-HDL.
