To Enter A Range In A Trace Expression - HP 64782 User Manual

Using the Emulation Analyzer

To enter a range in a trace expression

To enter a range in a trace expression
•
Use the command-line rules (described below) to create your
expression in the entry buffer. Then Choose Trace→After(),
Trace→Before(), or Trace→About(), as desired.
•
Using the command line, enter commands as follows:
•
To specify an address range enter:
address range <expression> thru <expression>
•
To specify a data range, enter:
data range <expression> thru <expression>
•
To specify a status range enter:
status range <expression> thru <expression>
•
To take the logical not of a range, use the not keyword before the range
keyword.
Ranges allow you to qualify analyzer actions on a contiguous set of values.
Mostly, you'll use address ranges to trigger or store on access to a data block
such as a lookup table. But, you can also use data ranges to qualify a trigger
or storage on a range of data values.
There is only one range term available in the trace specification. Once it has
been used, it cannot be reused. That is, if you specify a range in a trigger
specification, you can't duplicate it in the storage specification. (The
Terminal Interface does allow this type of measurement, though there is still
only one range term. Refer to the Hewlett-Packard MC6833x
Emulator/Analyzer Installation/Service/Terminal Interface Guide for
details.)
Since address is the default range type, you can omit the address keyword.
You can't omit the data or status keywords if those are the bus parts you
want to qualify.
