Chapter 12. SSN Modeling and Simulation

Dan Oh and Joong-Ho Kim

High-speed I/O interfaces commonly use differential signaling, because of its superior signal quality. However, mainstream memory interface designs still use single-ended signaling, such as Stub-Series Terminated Logic (SSTL) or Pseudo Open Drain (POD) I/O, because of its smaller pin count requirement and backward compatibility. Two of the most critical noise sources for single ended signaling are crosstalk and simultaneous switching noise (SSN). One can mitigate crosstalk by improving the physical design, such as using a flip-chip instead of wirebond, replacing microstrip with stripline, or placing ground guards. On the other hand, mitigating SSN is more challenging, because it ...
