The Trigger Tab
This function becomes true when a designated pattern1 is seen, followed
by a designated pattern2, and with less than a selected period occurring
between the two patterns. It uses two internal sequence levels.
• Find pattern2 occurring too late after pattern1.
This function becomes true when a designated pattern1 is seen, followed
by at least a selected period, before a designated pattern2 occurs. It uses
two internal sequence levels.
• Wait n external clock states.
This function becomes true after a number of user clock states you have
designated have occurred. It uses one internal sequence level.
Breaking Down and Restoring Functions
When you break down a trigger function, you gain access to all the
resource assignment fields and branching options. You can change
these fields to change the structure of the trigger sequence. You might
need to do this to create a custom trigger sequence or to add jumps.
To Break Down Trigger Functions
1. Select Modify in the Trigger window menu bar.
2. Choose Break down functions. The trigger sequence area changes to
show the entire trigger sequence as a series of user-level steps.
The contents of broken down functions are displayed in the long form
used in a user-level sequence step. If the function uses two of the
analyzer's internal sequence levels, (see page 89) both levels are
separated out and displayed in the trigger sequence area.
To Restore Functions
1. Select Modify in the Trigger window menu bar.
2. Choose Restore functions.
Use Restore functions to restore all functions to their original
