VRM Modeling: A Strategy to Survive the Collision of Three Worlds

This paper reviews four levels of VRM models that VRM designers, board level interconnect designers, semiconductor designers, and product managers often use to explore design tradeoffs throughout the PDN system. The choice of which one to use involves considering engineers’ levels of expertise and what problems they expect to analyze. Some tradeoffs and relative merits of the models are described.

EDI CON Conversations Offer New Insights

The third Electronic Design Innovation Conference (EDICON), was held Oct 17-18, 2018 in Santa Clara. The attendees were treated to two days of technical talks, tutorials and tradeshow with the overlapping topics of RF, SI, PI and EMI. This is a unique combination, allowing cross fertilization between these otherwise separate fields.

Life at the Low End

We usually associate problems with the power distribution network (PDN) as from excess VRM noise, or from transient current draw from the core or I/O drivers. But that’s not the only source of PDN noise. Some failures can arise from dull, boring, mundane problems at DC.

Why On-Die Power-Rail Measurements are Important

For this project, we will use an Atmel 328 microcontroller demo board, prepared with firmware to control it explicitly for our purposes, and with coaxial cables connected between the I/O pins and the input to the active probes of the scope. This interconnect provides a high bandwidth transmission line path for the signals.
