Senior Engineer

Sep 2015 – Dec 2019 · 4 yrs 3 mos

Developed Firmware code for chip bring-up and hardware validation for Giga DSL chip that includes various test cases for testing of hardware viz. PIO registers, DMA memories and validated network layer protocol packet insertion and extraction feature that helped the Hardware chip verification team. Got hands-on experience to understand and work on the DSL FDD Physical layer standard that uses advanced communication techniques like RS channel coding, Discrete Multi-tone and OFDM techniques. Debugged and tested various tickets raised by the SQA team. Wrote C code for processing various DSL features like Impulse noise monitoring sensor output processing, Loss of Signal detection, and validation of near end and far end error counters, code violation counters, etc. Worked on Open Source Review code clean up. Developed new soft skills: gvim editor, svn repository tool usage, code check-ins, teraterm scripting
