This contribution describes the work carried out by the INESC team, in collaboration with LIP, in order to increase testability features on the CMS ECAL upperlevel readout and trigger system.To accomplish this purpose, (1) extension of boundary scan test of electronic boards to system level, (2) introduction of self test in ASICs, (3) defect-oriented test effectiveness evaluation and (4) system-level modeling and simulation have been addressed and are reported.This work is consistent with the one carried out by Politecnico di Torino and CAEN in collaboration with CERN, in order to improve testability and reliability of the upper-level readout and trigger system.
