Using Storage Qualification
Store qualification enables you to store all data, no data, or just selected data,
before trigger occurs.
Example
The following statement determines that all occurrences of the bit pattern
you assigned to "a" will be stored before trigger occurs.
Setting < and > Durations (Timing only)
When a resource term is found during a timing sequence evaluation, you can
dictate how long the term must remain before the term actually becomes
true. When < or > duration is assigned, the secondary branching (Else on) is
not available.
Example
The following statement dictates the bit pattern you assigned to "a" must
appear and remain present for greater than 8 ns.
> Field When greater-than (>) is used, the analyzer continues sequence
level evaluation only after the resource term has been true for greater
than or equal to the amount of duration specified.
< Field When less-than (<) is used, the analyzer continues sequence
level evaluation only after the resource term has been true for less than
or equal to the amount of duration specified. For each (<) assignment,
you must delete 4 levels from the total number of sequence levels. So in
actuality, using a less than sign requires four sequence levels.
