mesh-based clock topology

Digital logic chips synchronize all logic operations by using a clock signal connected to flip-flops or latches, and the clock is distributed across the entire chip. The ultimate goal is to have a clock signal that arrives at the exact same moment in time at all clocked elements. If the clock arrives too early or too late from the PLL… Read More

Figure Gate Failing to Reach 1.1V

Synchronous circuits dominate the electronic world because clocking eases the design of circuits compared to asynchronous circuits. At the same time, clocking also introduces its share of challenges to overcome. No wonder, a tremendous amount of time and effort have been spent over the years on developing and implementing … Read More

Clock analysis rail to rail

Proper clock functionality and performance are essential for SoC operation. Static timing analysis (STA) tools have served well for verifying clocks, yet with new advanced process nodes, lower operating voltages, higher clock speeds and higher reliability requirements, STA tools alone can’t perform the kinds of analysis… Read More
