Digital-Mixed-Signal (DMS) Modelling using Signal Flow

Digital-Mixed-Signal (DMS) has taken over from Real-Number-Modelling (RNM) by providing a richer modelling capability of analog nets/components. While structurally connecting two-terminal devices together in arbitrary networks is possible it comes with its own set of challenges. The devices may be energy storage elements which have to be modelled as well. Instead of using a structural network a more efficient way is to signal transfer modelling techniques. This presentation aims to explain why and how.

Peter has worked in the industry starting back in 2001 when he joined a small company called Wolfson MicroElectronics, where he was project lead for more than 15 production devices. Since then, Peter has only worked at one other company, Nujira, before joining Dialog (now Renesas) at their Edinburgh office. Peter has been with Dialog since 2014. Peter’s background has been main digital design, but has over the years taken charge of many large mixed signal devices that are in volume production and been exposed to enough analogue design work to appreciate the issues they face in verification. Peter has an eye for looking for ways in which techniques can be done to improve chip level coverage, simulation runtime improvement to name a few. Peter is also in a unique position that during his days at Wolfson he was a key player in defining their schematic/Layout tool set with integrated revision control. This has allowed Peter to gather many skills not just in design work but in all the backend flows and EDA tools, understanding different netlist types and how the tools work.

Peter’s technical interests are mixed signal and analogue verification methodologies, design flows. Peter also is an Acellera SystemVerilog-AMS committee chair, UVM-AMS member/key contributor making sure the ‘users’ feedback on the language is considered and not what the vendors just want to support.
