Most integrated circuits (ICs) of sufficient complexity use a clock signal in order to synchronize different parts of the circuit, cycling at a rate slower than the worst-case internal propagation delays. In some cases, more than one clock cycle is required to perform a predictable action. As ICs become more complex, the problem of supplying accurate and synchronized clocks to all the circuits becomes increasingly difficult. The preeminent example of such complex chips is the mic… WebFigure 4.4: Clock tree trunk of Block 2 using the centred clock tree input pin with CCD algorithm. pp.93 Figure 4.5: Clock tree trunk of Block 3 using the reference clock tree input pin with CCD algorithm. pp.94 Figure 4.6: Clock tree trunk of Block 3 using the centred clock tree input pin with CCD algorithm. pp.95
