Signal Integrity


In today’s high-speed designs, the necessity of Signal Integrity (SI) is no longer up for debate. What is important? How to get the tools and, more importantly, the expert interpretation you need to solve your problems before they occur. If something is keeping you up at night and you want an opinion or need a simulation to resolve issues – call Fidus, let’s talk. Our SI experts are super smart, but also highly pragmatic – they’ll make sure your project is properly constrained.  You can relax – we’ve got it all under control.

We have really made our mark repeatedly advising on high-speed memory buses (e.g. DDR3/4), complex computing platforms, Interlaken systems (12.5Gbps links), FPGA transceivers (including GTH, GTX, GTZ), analog/digital isolation, complex layer stacks and mixed technology circuit boards (e.g. Rogers/FR4). Use the Fidus’ SI team for a couple days or a couple months and let them put your mind and project at ease.  You’ll be amazed at what they can do.

  • Pre- and post-route high-speed signal integrity analysis and simulation
  • 28GHz+ transceivers and 40GHz+ package level simulations
  • Signal integrity driven layer stacks and constraint generation
  • Net scheduling and design optimization for complex topologies like multi-drop buses (DDR3, DDR4)
  • Reducing reflections and crosstalk for improved timing margins and emissions
  • Optimizing decoupling for power integrity and lowest cost
  • Simultaneous switching noise considerations and design strategies
  • Component & system characterization, including full S-parameters, gain and noise figure optimization
  • Shield design and split plane optimizations for both sensitive signals and Regulatory Approvals
