Introduction to
the XCTL system
• Hardware controlling software used in
experimental physics
• Usage area:
– Analysis of semiconductor structures
– Displaying investigated structures in
graphical form
WSSEERE Meeting Ohrid, August, 25th - 30th, 2003

Example usage of XCTL
collimator
X-ray: monochr., parallel
X-ray: white (continuum)
photo plate

Features of XCTL
• Control motors (e.g. on sample holder)
• Control x-ray detecting devices
• Control measurement processes
– Adjust samples (before and during
measurements)
– Evaluate and display results (during and
after measurements)

XCTL activities
in the DAAD project
• Plovdiv
– Refactoring of use case LineScan finished
– AreaScan refactoring started
– Reports on both activities will be given at
this workshop
 A. Stoyanova, B. Botev, R. Gospodinov
Experiments with the XCTL system

XCTL activities
in the DAAD project
• Belgrade
– Applying URCA method to XCTL
– Realized with special version of XCTL:
• Ported to Win32
• Using environment simulation, only
– Successful application was possible
WSSEERE Meeting Ohrid, August, 25th - 30th, 2003

XCTL activities
in the DAAD project
• Novi Sad
– Translation of requirements specification
for use case Manual Adjustment
– By now version 2.2 available
– Very useful as a starting point when
dealing with XCTL for the first time
WSSEERE Meeting Ohrid, August, 25th - 30th, 2003
10
Progression of XCTL
at Humboldt University
• Reengineering of user interfaces
– Redesign of user interfaces of Manual
Adjustment and Topography
– More ergonomic versions with less errors
WSSEERE Meeting Ohrid, August, 25th - 30th, 2003
11
Progression of XCTL
at Humboldt University
• Porting activities
– New hardware without Win16 support
– Current hardware control logic not
supporting Win32
– Win32 device drivers for motor and
detector control developed by two of our
students
– Port finished
– Tests are running
WSSEERE Meeting Ohrid, August, 25th - 30th, 2003
12
Progression of XCTL
at Humboldt University
• Automated subsystem interface
recovery
– Refactorings and reengineerings dangerous
for whole system interactivity
– Automated recovery of the actually used
parts of the huge subsystem interfaces
– Using cross-reference data delivered by
SNiFF+
WSSEERE Meeting Ohrid, August, 25th - 30th, 2003
13
Progression of XCTL
at Humboldt University
• Visualisation of XCTL usage with
multimedia means
 U. Sacklowski:
Visualization of the use of XCTL
by multimedia means
WSSEERE Meeting Ohrid, August, 25th - 30th, 2003
14
Progression of XCTL
at Humboldt University
• ATOS: Automatic regression testing
– Regression tests required because of
continuous changes of XCTL
– Very time consuming and not very
interesting procedure
– Automatisation of this long tests and
their evaluation desired
WSSEERE Meeting Ohrid, August, 25th - 30th, 2003
15
Progression of XCTL
at Humboldt University
• ATOS: Automatic regression testing
– Script controlled test system for WINDOWS
applications
– Used for periodic and event driven
regression tests
– Similar functionality like commercial tools:
e.g. WinRunner

About the future
of XCTL in our project
• Students projects
– Extension of an existing system (e.g.
visualisation of motor moves)
– Analysis and review of an existing system
– Reengineering an existing system
– Real life software  highly motivated
students
WSSEERE Meeting Ohrid, August, 25th - 30th, 2003
20
About the future
of XCTL in our project
