2019 will be a big year for PCIe. With the approval of version 0.9 of the Base Layer for PCIe 5.0, implementers have a solid foundation to begin working on designs. PCIe 4.0 was introduced in 2017, before that the previous PCIe 3.0 was introduced in 2010 – ages ago in this industry. In fact, 5.0 is so close on the heels of 4.0, many products… Read More


How Good Are Your Clocks?

How Good Are Your Clocks?

One of the trickiest tasks in designing a modern SoC is getting the clock tree(s) right. The two big reasons for this:

  • the clocks can consume 30% or more of the power of the whole chip, so minimizing the number of buffers inserted is critical to keeping power under control
  • the clock insertion delay and clock skew have a major impact on

Properly Handing Of Clock Tree Synthesis Specifications
by Randy Smith on 04-28-2013 at 1:00 pm

Given today’s design requirements with respect to low power, there is increasing focus on the contribution to total power made by a design’s clock trees. The design decisions made by the front-end team to achieve high performance without wasting power must be conveyed to back-end team. This hand-off must be accurate… Read More
