    Mixed Signal Design IP Embraces Metric-Driven Verification Using RNM
    By Sathish Bala | 27 Aug 2012
    Even though it's been over 2 months since this year's Design Automation Conference in San Francisco, I am still surprised by the response that metric-driven, mixed-signal verification gets from our design community. Cadence had quite a few customer presentations at the EDA360 Theater at DAC this year. However, there was one presentation titled "Metric Driven Verification Approach for Analog/Mixed Signal IPs" authored...

    Mixed-Signal Gets Clear Message in China
    By QiWang | 10 Jul 2012
    While most of my colleagues in the US were taking a nice break during the July 4 th week, a small group of people including me was on the road for a mixed-signal Tech-on-Tour in China. There was some debate internally on whether designers in China would be interested in such a topic. What we had experienced last week was a clear (not mixed) signal from the IC designer community in China that they are hungry for knowledge...

    Managing Inherited Connections with CPF in Virtuoso
    By AndreasLenz | 23 May 2012
    Let's assume you are managing a schematic-driven top level design in Virtuoso and you want to import a digital block Verilog netlist into Virtuoso. This is a very common use model in mixed-signal implementation. While the Layout Database is saved in Open Access (OA), the optimized Verilog netlist needs to be imported into Virtuoso. Why use CPF? The Common Power Format (CPF) describes the design power intent for the whole...

    A Quick Tutorial on Managing ECOs Using Pcells in Mixed Signal Designs
    By paragb | 16 May 2012
    The purpose for creating a Pcell is to automate the creation of data. Pcells should be designed as standalone entities, independent of the environment in which they are created and independent of the variety of environments in which you or someone else might want to use them. An environment can react to a Pcell, but Pcell code should not react to, interact with, or be dependent on an environment. Although it is possible...

    CDNLive! -- Real Number Model Development and Application in Mixed-Signal SoC Verification
    By AElzeftawi | 9 Apr 2012
    With the escalating complexity of analog mixed-signal (AMS) chips, increasing digital content in response to new functionality demands, and steady growth of IP blocks into larger and larger SoCs, traditional AMS verification flows are becoming inefficient in handling full chip verification. High-performance digital verification and high accuracy analog verification represented the foundation for traditional AMS verification...

    DVCon 2012: Bringing Continuous Domain into SystemVerilog Covergroups
    By PrabalB | 30 Mar 2012
    On the last day of February 2012, I presented a proposal at the DVCon 2012 Conference to extend SystemVerilog to support a real data type in coverpoint objects in order to facilitate mixed-signal verification for functional coverage. The paper, titled “ Bringing Continuous Domain into SystemVerilog Covergroups, ” reflected a year-long effort between Cadence R&D and Scott Little of Freescale (Scott moved to Intel just...

    Behavioral Model Validation with amsDmv
    By xiuya | 30 Nov 2011
    a msDmv (Analog Mixed Signal Design and Model Validation) is an application integrated in the Cadence Virtuoso GUI flow and it can also be invoked from command line with some feature limitations. amsDmv can be used to compare the simulation restults and design interface (pins) from the DUT with those from the reference design. Therefore users can use amsDmv to validate behavioral models with original transistor level...

    Managing ECOs in Mixed Signal Designs
    By Benatcdn | 29 Sep 2011
    Imagine you are days away from completing the implementation of a fairly complex mixed-signal design, and you are already day-dreaming about the vacation you have planned in a few weeks. Then it happens -- the dreaded change in the design requiring ECOs to digital or analog content, or worse yet, implementation problems that need fixing. Should you call the travel agent to see if you can still buy travel insurance...

    Bringing Static Analysis Methods to Mixed Signal Designs
    By RajendraPratap | 26 Aug 2011
    Accurate static analysis and complete coverage of the functional space remain very challenging for mixed-signal designs. The functional verification of mixed -signal designs has never been completely possible. It is very common to use behavioral models of analog/mixed-signal blocks during the full chip functional verification stage, and to use .lib timin g models during the physical implementation stage. There...

    Synchronizing Designs and Behavioral Models in Mixed-Signal Flows
    By Paul Foster | 6 Jul 2011
    The creation of behavioral models is only one part of the process of using those models in a mixed-signal design verification flow. If the model and design don't match, the effort is worthless. Even worse, it can damage the entire design verification process. "Why should I care about keeping my behavioral models and designs in synch ?" The benefit of using a bottom-up behavioral model to improve design...

    How to Design Analog/Mixed Signal (AMS) at 28nm
    By nizic | 21 Jun 2011
    Wireless, networking, storage, computing and FPGA applications have been moving aggressively to advanced process nodes to take advantage of lower power consumption, improved performance and area reduction. Today, most of these applications integrate a significant amount of analog/mixed signal (AMS) or RF together with digital circuits. Since AMS often occupies over 50% of the chip area, applying traditional, conservative...

    Mixed-Signal Physical Design Implementation Made Easy
    By RajendraPratap | 16 Jun 2011
    Getting a complex mixed-signal design assembled and completely analyzed for mask design is a huge challenge today. The IPs are complex and too many decisions need to be made to meet design budgets. All this is not possible with anything less than a fully automated, front-to-back mixed-signal design solution. On top of mixed-signal complexity, battery operated wireless and hand-held mobile applications are extremely sensitive...

    CPF Low Power Simulation with Analog and Mixed-Signal Design (CPF-AMS)
    By Qingyu Lin | 23 May 2011
    We have been talking about low power simulation and the Common Power Format (CPF) for five or six years now. It’s become popular in most digital designs thanks to a mature methodology and design flow. However, more and more SoC designs are coming up with mixed-signal content. How will low power technologies and formats be used in mixed-signal design? For SoC design verification, we always involve an analog solver...

    Is China Ready for Next Generation Mixed-signal Design?
    By QiWang | 18 Mar 2011
    A Chinese design engineer told me that his manager once told him: "You do not have to have creativity but you must know how to imitate!" This is kind of a reflection of the rapid technology growth in China for the past decade, where many of the technology advancements came from learning the latest and best technologies from the West. When we planned for the worldwide Cadence EDA360 Tech-On-Tour mixed-signal seminars...

    Advanced Mixed-Signal Designs Demand a Unified Methodology
    By nizic | 6 Feb 2011
    Mobile, automotive, consumer and medical applications require the productive realization of large and complex mixed-signal systems in silicon, and they must be on time and within budget constraints. Process capabilities make it possible to implement analog and RF circuits in CMOS technology at advanced nodes, and to integrate analog and digital functionality at the system-on-chip (SoC) level. However, mixed-signal SoC...
