that provided min/mid/max input values to verify robustness and complete coverage analysis of dynamic and static

conditions in the Ada 95 software. The AdaTEST utility was used to verify structural coverage events that were not

exercised or linked during requirements coverage testing. The following events were verified: positive and

negative initialization was used to check for code containing unintended functions; every entry and exit condition

was invoked at least once; deactivated code for future versions was not executed; and, dead code was not executed.

AdaTEST generated the test scripts for testing and an output file containing pass/fail results for all test conditions.

The verification conformed to DO-178B Level D.

Software Engineer – Contract Position 02/08 – 07/08

Rockwell Collins Inc., Melbourne, FL - Avionics RTEM Software

Created test procedure for verifying an Ada 95 software revision to the function that decodes Morse code signals in

the ADF-900 Auto-Direction-Finding radio’s real time embedded software. A black box verification methodology

was utilized using simulated Morse code inputs to the radio from the Labview software tool, which created Morse

signals of varying pulse widths and timing intervals to fully test the performance software level requirements of the

radio. Created test procedure for verifying the Error Detection and Correction (EDAC) utility in the GLU-925

Global Landing Unit Satellite radio. Text macros were written to verify the software level requirements for the 4

registers that performed the EDAC function. The Excursion server utility was used to create a UNIX xterm shell

from which the Rational Apex program’s debugger function was run. An additional xterm shell was used to access

the HP 64789C Intel 80386EX Emulator/Analyzer, which had the capability of reading from, and writing to,

memory for verification of the outputs from the radio. Each macro was run as input in the emulator shell, and a

UNIX script file was created to log the results. A Visual Basic program was written that post-processed the UNIX

log files to print pass/fail results. Development, verification and validation conformed to relevant DOD standards

and RTCA/DO-178B Level B.

Software Engineer/Programmer – Contract Position 06/03 – 01/06

Pratt & Whitney Corporation, East Hartford, CT – Aeronautics Software for Military Jet Engines

Developed, designed and programmed Ada 95 code with a VAX/VMS platform for an ALPS (Advanced Life

Prediction System) Simulator that predicted the “Life” expectancy for components used in F-35 JSF (Joint Strike

Fighter) jet engines. The Matlab/Simulink software tool was utilized to build the test-bed driver for the ALPS

simulator, and to verify all software requirements. For each model representing an engine component, a separate

Ada software package was written that computed the predicted damage accumulation of that component for each

origin-to-destination flight of the JSF aircraft in which the engine was installed. A C++ cross-compiler was used to

compile, link and build the Ada 95 code into the corresponding C++ code required for input to the

Matlab/Simulink test bed. An Ada software subsystem was programmed for a Real-Time Engine Model (RTEM)

on the VAX/VMS test bed, which read the raw analog data from the engine’s sensors (temperature, pressure, gas

flow, etc.) and then processed and formatted it for input to the ALPS Simulator’s Ada 95 code . The RTEM

subsystem utilized a Texas Instruments DSP to convert the raw analog data to digital format and filter noise from

the raw data. The ALPS Simulator’s outputs were graphic displays to verify the requirements for each engine

component’s damage accumulation computed from the RTEM input data, where a “Life” index value of zero

represented a new component, and a value of one indicated the component required replacement. Various types of

damage were predicted, such as oxidation, corrosion, creep, crack growth, and high and low level cycle fatigue.

Each Ada 95 model on the VAX/VMS test bed was verified utilizing waterfall and black box verification

methodologies; i.e., specified RTEM parameters for the various engine and flight conditions were input to an Ada

95 software model, the actual values of the corresponding actuator outputs were read and compared with the

expected values, and a pass/fail result was given accordingly. As a Technical Writer, created Software

Requirements Specification (SRS), Software Design Document (SDD) and Software Development Plan (SDP) for

the ALPS Simulator’s software. Development, verification and validation conformed to relevant DOD standards

and RTCA/DO-178B Level A.

Software Engineer - Contract Position 09/99 – 01/02

Pratt & Whitney Corporation, Palm Beach Gardens, FL – Aeronautics RTE Software for Military Jet Engines

Member of team that created test plans, test procedures and test scripts to verify software level requirements for the

real time embedded software used with JSF jet engines. The engines were to be installed on JSF F-22 and F-23

aircraft. Each test case in a test script verified a particular software level requirement for a particular software

module, and the Software Development Plan (SDP) and Software Design Document (SDD) were updated

accordingly. The SDP utilized ‘anchors’ (place markers) in the Ada 95 code that were cross-referenced to ‘anchors’

in the Software Requirements Specification (SRS) document, which delineated all high and low software level

requirements agreed upon with the vendor and was modified to reflect the requirement changes. A FADEC (Full

Authority Digital Engine Control) simulator, based on a VAX/VMS platform, was utilized to emulate aircraft flight

conditions and the parametric values of the engine’s sensor inputs and actuator outputs. A PC based on Windows

NT 4.0 operating system was used in conjunction with a SUN workstation based on a UNIX operating system to

run the automated test scripts. A black box testing methodology was used; i.e., the applicable FADEC outputs

representing flight conditions and engine sensor parametric values were used as inputs for each test case in the

automated test script, whereupon the actual and expected output values of the relevant actuator were compared for

a pass/fail result. The Object-Oriented Design (OOD) code was implemented in Ada 95 language, based on a

VAX/UNIX platform/operating system. The Unigraph utility was used to create data flow diagrams showing the

code path traversed by each parameter during the execution of the test case. Test review walkthroughs were held

with the software development team. Development, verification and validation conformed to Ada 95 coding

standard, relevant DOD standards, and RTCA/DO-178B Level A.
