Chapter 11. Scriptor
Using the Analyzer Scriptor feature, it is possible to send/receive packets, extract fields from a packet and
display the results on a Control Panel by using different kinds of indicators. The Scriptor window is divided
in four parts, each represented by a tab page.
· Script Editor
·
Control Panel
·
Data Editor
· Script Properties
For a quick impression of the features of the Scriptor, see the following examples:
· simpleSend : A script showing how to define a packet using the built-in macros and how to send the
packet multiple times.
·
simConfRom : A script showing how to handle the configuration ROM read requests using a data file
such that the presence of a configuration ROM is simulated.
·
timedSend : A script showing how to define a packet using the built-in macros and how to send the
packet at user-controlled frame offset times. This example makes use of the Mil1394 Protocol and will
only work if Mil1394 mode is enabled.
· erroneousSend : A script that allows the user to send packets that contain errors. The control panel is
used to select what kind of error the packet should contain and to set some other options.
·
Mil1394MessageMonitor : A script for the Mil1394 Protocol that displays signal values for a specific
message ID and channel number. Up to 20 signals can be configured and displayed simultaneously.
This example will only work in Mil1394 mode.
The Script Editor can be used to enter scripts for the Analyzer device. To make the Scriptor functionality
as intuitive as possible, assistance is provided by showing relevant property editors while entering the
script. These property editors are shown to the right of the Script Editor and can be used to fill in function
parameters, loop conditions and much more.
The Control Panel contains a wide range of indicators for showing the values of user-defined parameters
in a graphical way. Alarms can be set by specifying parameter conditions. It is also possible to send
values from the control panel to a running script, thereby controlling it.
The Data Editor contains different kinds of editors for entering constant data which can be used by the
script to write to a packet.
The Scriptor can be used to control almost anything of the Analyzer, including packet sending and
reading/writing of Phy registers. For a reference of the script language and API, see the Language
reference and Function List section of the manual.
