Hints to Make
Setting Up the
Sequencer Easy
When you become experienced at using the "complex" configuration,
you will be able to simply enter the trace commands for the measure-
ment you want. Until then, following the steps listed below may make
it easier for you to set up the sequencer.
1. Write down the sequencer algorithm.
2. Draw the sequencer diagram.
3. Define the trace patterns (tpat) and range (trng).
4. Specify the primary and secondary branch expressions (tif, telif).
5. Specify the trigger term (tsq -t X)
6. Specify the storage qualifiers (tsto).
Generally, you will always follow steps 3 through 6 when setting up the
sequencer in the "complex" configuration. In reality, you will probably
perform steps 1 and 2 at the same time, but here the algorithm is ex-
plained before the sequencer diagram is presented. Once you become
experienced with how the sequencer works, you may be able to visual-
ize steps 1 and 2 without having to write anything down.
Write Down Sequencer Algorithm
It is a good idea to write down what you want the sequencer to do. A se-
quence term can be used to "search" for some trace state; this is a se-
quence term with a primary branch expression but no secondary branch
expression.
A sequence term can also be used for conditional branching; this is a se-
quence term with both primary and secondary branch expressions. If
some trace state occurs, then go to sequence term X (primary branch).
Else, if another trace state occurs before the first, go to term Y (secon-
dary branch).
Either branch may be to any sequence term. If a state satisfies both the
primary and secondary branch expressions, the primary branch will be
