Troubleshooting problems

It's possible that problems or conflicts occur while working with the Clocks Tool. Such problems and the overall status are indicated in red on the central status bar of the Clocks Tool. The status bar displays global information on the reported problem.

You may encounter any of the following problems:
  1. Requirement(s) not satisfiable: Indicates that there are one or more locked frequency or frequency constraints for which the tool is not able to find a valid settings and satisfy those requirements.
  2. Invalid settings or requirements: [element list] – Indicates that the value of a settings is not valid. For example: The current state of settings is beyond the acceptable range.
The following are some tips to troubleshoot encountered problems.
  1. Find the elements and settings with marked errors in the diagram or tables and see the details in the tooltip.
  2. Start with only one locked frequency and let the tool find and calculate other ones. After you are successful you can add more.
  3. Go through the locked outputs, if there are any, and verify the requirements (possible errors in the required frequency, wrong units, and so on).
  4. If you are OK to have a near around of the requested value, right-click and from the pop-up menu select Clock output > Find near value.
  5. If you cannot reach the values you need, see the clock paths leading to the clock output you want to adjust and check the selectors if it's possible to switch to another source of clock.
  6. Try to remove locks by selecting Clocks > Unlock All Settings. In case many changes are required, you can simply reset the model to the default values and start from the beginning. To reset, select Clocks > Reset to processor defaults.
You can resolve most of the reported problems using the Problems view. Each problem is listed as a separate row. The following options appear when you right-click on a selected row in the Problems view.
