Fanout-Induced Delay fanout => higher loads => larger delay Measure delay with fanout... bufns: dedicated buffers ideal case, delay=1 delay independent of fanout buf: shared buffer drives triple load delay doubles bufp: pass-T input fanout limited to internal pass-T nodes low delay increase bufm: mux input fanout limited to internal mux nodes very low delay increase Normalized Delay.
