Robert Bosch, Farmington Hills, MI [Nov’06–Mar’09]

Position: Software Engineer

Client: Volkswagen Audi, Germany

Requirement was to introduce new Cordieritsubstrat system inside the existing Diesel Particulate Filter

(DPF). The current software was not designed for Cordieritsubstrat system where regeneration temperature

is more in the DPF‘s temperature. Change was to minimize the current temperature in current design and

introduce thermal protection for Cordieritsubstrat DPF.

Responsibilities:

Feasibility study of system requirement.

Modeling of system requirement using ASCET.

Programming the modeled design using Embedded C.

Black Box unit testing done on an open loop Lab Car. White Box testing done on an onboard Tricore

custom specific target hardware.

Design and develop databases to maintain different version of the hardware using SQL server and

access the same and test the software developed.

System testing using closed loop lab car.

Integration of software to the main server using Rational ClearCase and automate the new integrated

files, test results using Perl scripting.

Configuration management in charge for the project to maintain all the quality related records as per the

standards.

CMMI level 5 process is used in software life cycle for deliverables (executables and customer

document).

Environment: C, ERCOS, SQL Server, ClearQuest, INCA, ClearCase.

Client: General Motors, North America

Engine Control Module can transmit and receive group of CAN frames, selection of the groups are decided

based on vehicle variants, like OPEL Vectra, OPEL Astra etc. Each vehicle variants based on the customer

vehicle configuration can have 'n' number of CAN nodes where each node represents a Controller. The

customer required a flexibility to select a group of CAN frames for a particular vehicle configuration. This is

achieved by introducing a Data Identifier (DID) using End Of Line (EOL) programming via tester which

programs EEPROM cell. Each bit of the cell represents the presence of a key node.

Responsibilities:

Study usage of communication protocols.

Design and simulation of CAN frames using CANoe with virtual network.

Configuration and Implementation of CAN frames.

Implementation of interface function between application software and complex drivers of CAN

hardware layer.

Develop a new database using SQL Server which holds the different set of data for CAN frames and

test for the response.

The reliability of the design was tested under Open Loop Lab car condition with the help of CANalyzer.

Integration of software to the main server using Rational ClearCase.

Configuration management in charge for the project to maintain all the quality related records as per the

standards

The requirement was to check differential pressure across the particulate filter and the sensor is monitored

for errors.

Responsibilities:

Analysis of diagnostics in the system.

Modeling of system requirement using ASCET.

Programming the modeled design using Embedded C, C++.

Code optimization.

Automation test done on an open loop Lab Car.

Robert Bosch, Bangalore, India

Position: Software Engineer

Client: General Motors, North America

Requirement was to Implement Four Wheel Drive (FWD) and All Wheel Drive (AWD) functionality.

FWD/AWD functionality is needed for off road vehicles where there are reduced tractions between the

wheels and the road. The detection of traction is sensed by the Transfer Case Control Module (TCCM)

Engine Control Unit and locks the central differential which splits the torque between primary axles and

secondary axles.

Responsibilities:

Interacted with onsite project managers to collect analysis and program the requirements using C.

Test using closed loop lab car and integrate the new code using ClearCase.

Worked with the QA team and prepared QA reports.

Environment: C, ERCOS, ASCET, ClearQuest, ClearCase, Shell Scripting.

Infineon Technologies, Bangalore, India [Apr’04-Nov’06]

Position: Technical Consultant

Project: Stack Depth Analyzer and Checksum Generator

This tool reports stack usage of a particular Tricore application from its linker output. The linker output (.elf)

is generated using the TASKING compiler build output process. This tool tracks the application user stack of

Tricore. Develop and automate test cases to track the call tree, stack depth for different optimization level of

the code for different scenarios.

Responsibilities:

Design and develop the requirement using C, C++.

Automation of test cases and acceptance testing.

Preparation of detailed bug report.

Integration of software to the main server using Rational ClearCase.

Environment: C, C++, ClearCase.

Project: Functionality Validation of TASKING 16 bit Compiler, in-house SDCC Compiler

Design and port SDCC in-house compiler for Infineon microcontrollers and functionality validation of stable

compilers. Develop test cases to test compiler specific features.

Environment: C, C++, ClearCase.

Project: Minimon debugger.

Functionality validation of Minimon debugger.

Responsibilities:

Develop test cases to check the absolute addressing, special functional registers, program memory,

external memory, internal memory.

Test for the debugger features like conditional and unconditional breakpoints setting by writing test

cases on basis of hardware.

Test to check the watch variable window updating for local, global variables in the test case.

Develop test cases to test debugger crash.

Test for all the debugger commands like connect, disconnect, reconnect, download, go and many.
