Projects
The following are some of the projects that I have been involved in during my time at IIT Madras.
Incremental Timing and Common Path Pessimism Removal (CPPR) Analysis
TAU 2015 Contest Dec 14 - Mar 15
Guide: Dr. Nitin Chandrachoodan Report
- The project included developing a unified academic tool for timing verification to analyze and ensure slack integrity and timing closure in VLSI design flow.
- Developed a timer that supported incremental changes to a circuit (in standard industrial formats), performed fast timing analysis to the affected regions and removed pessimism due to common data and clock paths (CPPR) using least time and resources.
- Developed novel techniques to identify and report worst slack paths in a circuit.
- The timer won international 3rd place in TAU 2015 Contest and was presented at ICCAD 2015.
iitRACE: Incremental Timing Analysis Engine
Master Thesis Project Jun 15 - Present
Guide: Dr. Nitin Chandrachoodan
- The project includes developing a multi-threaded implementation for incremental timing framework.
- Developed effective pruning techniques to make timing analysis faster without compromising on memory usage.
- Currently working to include gate-sizing and threshold-voltage swap for leakage power optimization in the tool.
Radiation Pattern Measurement System for Automotive Radar
Project Intern, Wireless Connectivity Solutions, Texas Instruments May - July 14
Guide: Chethan Kumar Y B Report
- Developed an automatic radar positioning system for radar modules testing.
- The module provides easy control of radar position in 3D space with angular position error less than 1 degree in both horizontal and vertical plane and range error less than 1 mm.
- It is now used to test characteristics of automotive radars used for automatic car parking.
Solar Charger for Hearing Aid Devices
Project Intern, Flexitron India May - July 13
Guide: R S Hiremath Report
- Developed a pocket solar charger for R13 size batteries used in BTE Hearing aid.
- Designed energy efficient circuits for dual mode charging (AC as well as Solar).
- The product won National Award for the Empowerment of Persons with Disabilities 2013.
- The product is now produced in mass volumes and supplied to health organizations all over India.
