Question

When running the VARIANTS command from DE-HDL console window, system returns the message "Cannot proceed to open Variant information as the variant data is in use by user".  


How do I correct this issue?

 

Solution

This message is displayed when a .lck file is present in the directory worklib/<design_name>/variant.   This may be an orphaned file in which case it can be deleted.  


This .lck file may also be present if the Variant Editor was launched from the Projmgr using TOOLS > VARIANT EDITOR before attempting to run the VARIANTS command option in DE-HDL.  

 

In this case select FILE > SAVE and then FILE > EXIT from the Variant Editor. The .lck file is removed and now allows the VARIANTS commands in DE HDL to be successfully launched.
