Description:
Triconex Westlock is a railway signal interlocking system; it is an
arrangement of signal apparatus that prevents conflicting movements through
an arrangement of tracks such as junctions or crossings
. Signals may not be operated to permit conflicting train movements to
take place at the same time.
. Switches and other appliances in the route must be properly 'set' (in
position) before a signal may allow train movements to enter that
route.
. Once a route is set and a train is given a signal to proceed over that
route, all switches and other movable appliances in the route are
locked.

the gap.
Project#5
Title : Enhanced Ground Proximity Warning System-EGPWS, Level C
Tools : LDRA, PVCS, BOSS, Clear Case and Clear Quest
Duration : July 2010 to Mar 2011
Description:
The EGPWS is a terrain awareness and alerting system providing terrain
alerting and display functions with additional features. The EGPWS uses
aircraft inputs including geographic position, attitude, altitude,
airspeed, and glideslope. These are used with internal terrain, obstacles,
and airport databases to predict a potential conflict between the aircraft
flight path.
Additionally, the EGPWS provides alerts for excessive glideslope deviation,
too low with flaps or gear not in landing configuration, and optionally
provides bank angle and altitude callouts based on system program pin
selection.
Responsibilities:
. Developing the unit test cases for the requirements/functions
. Developing the system tests for the given requirements
. Prepared test plan and test cases document
. Review of the unit test cases/ system tests developed by other team
people

reports.
Project#6
Title : Global Navigation System Sensor -GNSS, Level A
Tools : Bullseye, DOORS, SVN, Vision ICE Emulator, and ATE.
Duration : Aug 2008 to June 2010
Description:
GNSS is also called as Global Navigation Satellite Systems; it is the
standard generic term for satellite navigation systems ("sat nav") that
provide autonomous geo-spatial positioning with global coverage. GNSS
allows small electronic receivers to determine their location (longitude,
latitude, and altitude) to within a few meters using time signals
transmitted along a line-of-sight by radio from satellites.
Responsibilities:
As part of V&V team I have developed the test designs and test scripts for
given requirements. Developed white box scripts where we have used Vision
ICE hardware to interact with the sensor board, and tested requirements.
And as part of structural coverage team, I have analyzed the code which is
not covered and classified the type of gap (Requirement, Test, Dead code or
Exception). Since GNSS software is a level A software we did MCDC coverage
(complying with DO-178B standards) where we need to check TRUE and FALSE of
every condition. We used Bullseye tool for the coverage report.
. Requirements Based Testing- White box scripting using Vision CLICK
Emulator and Black box using ATE Toolkit.
. Structural Coverage analysis and coverage hole fixing
. Debugging white box bench issues
. Reviewing test designs and test scripts using eReview tool.

Title : Integrated Navigation Radios (INR), Level A
Tools : ABC Scat and WINBOSS
Duration : Jan 2008 to July 2008
Description:
As part of SCA team, I have analyzed the code which is not got covered. The
uncovered line of code we treated as hole or miss. I have analyzed the
uncovered conditions whether they are due to Requirement hole, Test hole,
Dead code or any Coverage Exception category. Misses will be generated by
the ABC Scat tool.
Responsibilities:
. Instrumenting the code for the individual module (there are around 20
modules in the INR) by using the ABC Scat tool.
. Identifying the test scripts that are traced to the individual module
in the DOORS.
. Loading the instrumented binary file onto the Test Bench
. Executing the test scripts on the Test Bench as per the configuration
(there are several modes of operation like ILS, GLS, MB and FLS).
. Generating the report for the appropriate module by using the ABC Scat
tool
. Gap Analysis: Analyzing the gaps whether they are due Requirement
hole, Test hole, Dead code or any Coverage Exception category.
