- Board bring-up- Modify validation test codes for new product - Add new features to Linux test system

– 4 years experiences of board bring-ups that validates boards electronically and functionally as well as runs reference codes on it– 5 years experiences to develop firmwares for several peripherals that include DMA, IIC, IIS, Clock, Power, etc.– 5 years experiences to figure out troubleshoots by debugging reference boards and reference codes with debuggers, oscilloscopes, multimeters, function generators, and power supplies– 4 years FA(Failure Analysis) experiences to define exact phenomenons and find out clues that were given to co-workers and customers to make the solutions– Developed and reorganized validation processes as well as an automatic test system to increase test coverages by 60%– Analyzed analog and digital characteristics of silicon chips by using debuggers, oscilloscopes, multimeters, function generators and power supplies– Ported validation programs to a Linux test system and an embedded system(uC/OSII) to detect problems under a multiprocess environment– Developed automatic mass production systems to guarantee products’ quality before those were shipped to a customer ∗ A hybrid system that mixed an FPGA chip with multiple ARM chips to communicate with each other ∗ Modified and enhanced prior systems so that product yields increased by 0.2%– Developed a pseudo OS that made it easy to update its software, and reduced a total test time and a failure rate by 0.1%– Developed a high-speed, high-performance 64-bit DMA IP in Verilog HDL to increase data transfer speed by 6 times than prior one
