Abstract—This paper aims to propose some more efficiency design to escape the key IC chips shortage in current entry level LDM. The direction in the paper will include to replace the high-integrated IC chips with discrete ones; use local IC chips to achieve basic functions in LDM; integrate the function design to decrease the critical IC chips usage.   

Keywords - discrete IC chips; functional safety; integrate function
