Micro and Nanotechnology research for you

Group overview

The group has a wide expertise in the study of the procedures and the techniques which help to determine the origin of the fail (malfunctions, destruction) which happen using electronic components, in order to determine the actions to correct and eliminate the failures, increasing the reliability of the systems.

Together with the CAD Service, our experience in the design field includes the modeling, simulation and synthesis of circuits, IPs and growing to systems on chip (form VHDL/ Verilog to ASIC/FPGA), Support and Training to users, purchases and general management of CAD, CAD development for internal use, Libraries and design kits development for internal and external technologies, Management of external kits Back-end: P&R, delay extraction/back-annotation and post layout functional and Fault simulation.

These skills allow us to cover from the analysis to the top-down reconstruction of integrated circuits, performing in these process the identification and study of the different blocks that form them.
