Developed validation suites for peripheral modules for dsPIC and PIC32 microcontrollers:SPI: Serial Peripheral InterfaceCTMU: Charge Time Measurement UnitI2C: Inter-Integrated CircuitRAMFLASH (NVM)USB (Universal Serial bus)OscillatorsDeveloped Enhanced Validation suiteDescription: To Automate the whole process of validation for legacy peripheral modules using LabVIEW and Microchip tools. This was recognized and certified by Microchip Team which reduced human intervention, lesser bench setups and faster silicon validation. Validation of these modules are performed under different voltage and temperature conditions.Developed Speed Test SuiteDescription: To find the performance of the dsPIC or PIC32 microcontrollers with respect to clock speeds, active currents, different operating voltages and temperaturesDeveloped Peripheral current measurementsDescription: To automate and find active current consumption of individual peripheral modules of the microcontroller under different voltages, temperatures and process corners.

Worked and designed Automated Data characterization system for PIC microcontrollers as part of my project work during MSc. The GUI measures, collects, tabulates and analyse the data points of different parameters of the AC & DC characteristics of Microcontroller.This project was recognized at top level management and continued to use as tool for characterization. This also helped me fetch Applications engineer position at the same company.
