In a recent study done by McKinsey and IDC, we see that physical design and verification costs are increasing exponentially with shrinking transistor sizes. As figure 1 shows, physical design (PD) and ...

At a logical level, synchronous designs are very simple and the clock just happens. But the clocking network is possibly the most complex in a chip, and it’s fraught with the most problems at the ...

High performance clock buffers — those without phase-locked loops (PLLs) — are often used in communications designs for duplication, distribution and fanout of clock signals. Sensitivity to long-term ...

Figure 1: Artist's impression of future clock networks that use laser links (red) to synchronise clocks on the ground and onboard satellites. Newbury and co-workers [1] have demonstrated that such ...
