As a Semi-Custom Physical Design engineer, you will excel in all phases of Physical Design of sophisticated Analog Mixed Signal designs from RTL to delivery of our final GDSII. Your responsibilities include but are not limited to the following:- Generate block level static timing constraints.- Build block level floorplan including pin placement and power grid.- Develop and validate advanced low power clock distribution network.- Perform block level place and route and close the design to meet timing, area and power constraints.- Generate and Implement ECOs to fix timing, noise and EM IR violations.- Run Physical Design verification flow at block level and to provide guidelines to fix LVS/DRC violations.- Participate in establishing accurate CAD and Physical Design methodologies by construction designs.- Assist in flow development for Analog-On-Top integration.- Crafting sophisticated layout for mixed signal, and analog circuits in deep sub-micron CMOS technologies.
