Document Table of Contents Canceling Script Branches

You can cancel a suspended script branch by interrupting it using the interrupt-script-branch command. Each branch has an ID associated that can be found using list-script-branches, and that is returned by the script-branch command.

The following capture shows an example of the use of these commands. In this example, a branch is created that waits for 10 CPU steps and the output of this command, which corresponds to the branch ID, is stored in the $id variable. The ID identified is 4. Use the list-script-branches command to verify this. From this command, you can see the condition for which the branch is waiting to continue its execution. Then, advance in the simulation 5 steps, which is not enough to achieve the condition required. At this point, interrupt the branch using the interrupt-script-branch with the ID as an argument. You receive a message indicating that the branch was interrupted. Call the list-script-branches command again to confirm that the branch is no longer in the list.
