Design Meets EDA: Gaps And Countermeasures In Analog/Mixed-Signal IC Design

Along the path from specification to silicon, the design of analog/mixed-signal chips comprises a variety of challenges. They are of technological, methodological, organizational, communicational, and business nature. Additionally, large gaps are to be managed among the individual challenges. Still up to now, approaches such as the “four eye principle” are used even in industrial practice i... » read more

AnastASICA — Towards Structured and Automated Analog/Mixed-Signal IC Design For Automotive Electronics

In our world based on electronics, the design of analog/mixed-signal (AMS) ICs is still mainly done manually. While digital design benefits from complete synthesis flows, analog lags far behind in terms of development time, cost, and risk. Analog design flows are hardly standardized and necessitate the four eye principle as important quality tool. Thus, highly experienced designers who incorpor... » read more

From Constraints to Tape-Out: Towards a Continuous AMS Design Flow

Author(s): Krinke, Andreas; Horst, Tilman; Gläser, Georg; Grabmann, Martin; Markus, Tobias; Prautsch, Benjamin; Hatnik, Uwe; Lienig, Jens The effort in designing analog/mixed-signal (AMS) integrated circuits is characterized by the largely manual work involved in the design of analog cells and their integration into the overall circuit. This inequality in effort between analog and digital... » read more

The Art Of LP Analog

The best way to reduce power in analog chips is to make architectural changes or adopt a new architecture for the individual block. However, there are also some design techniques used to reduce power in analog circuitry. Unlike digital circuitry, which allows an engineer to leverage a low power library and optimize through a constraints file with the EDA software to reduce power, the same do... » read more

Power And Noise Integrity For Analog/Mixed Signal Designs

The convergence of advance process technology, increasing levels of integration, and higher operating frequencies pose considerable challenge to IP designers whose circuits are required to function in variety of conditions. Full-custom and mixed signal circuit designers ensure that their circuits will function by simulating for various operating conditions (PVT, input stimuli, etc). One key asp... » read more

Good Times For Analog Designers

By Ann Steffora Mutschler For a number of technological reasons, analog/mixed-signal design and low-power design are converging, and with that comes both challenges and opportunities. As far as challenges go, process variations at 14nm, 20nm and even 28nm have increased significantly to include DFM impacts such as layout-delay effects. On the digital side, those process changes affect... » read more
