[SI-LIST] : Output driver versus internal logic switching noise

Hello,

I'have been reading in several switching noise related papers that
traditionally the only important source of noise in ICs was due to the
simultaneous switching of the output drivers but that in today circuits the
switching noise generated by the internal logic would be also very
important. Does anybody have quantitative confirmation of this? It is any
study of the ratio between internal logic/output driver switching noise in
any commercial IC or ASIC?

Thanks in advance

Jose Luis Gonzalez
