Honored ContributorSome options are greyed out most likely because the lock mode is set to "allow trigger condition changes only". The wording doesn't make much sense. I interpret it as "don't allow any change that requires compilation". This lock mode is selectable near the top of the setup tab above the column called "Data Enable". If you start SignalTap using the standalone version, this lock mode is automatically set. You can just change it to be "Allow all changes".
This lock mode sometimes helps me understand what change requires compilation and what doesn't. After using this tools for a while, I don't really need it anymore. The fact that adding node is allowed is probably an error, I think.
