|Analog Insights: Analog/Mixed-Signal Design and Verification Blog|
Welcome to Analog Insights! Our goal is to have an innovative, informative and interactive blog about AMS, from purely analog to mixed signal and RF. AMS is a challenging and fast paced place, so let’s have fun with it and mix it up! I hope you enjoy this blog.
Interestingly, I have been wanting to be an engineer since a very young age. After getting a degree in Doctoral studies in EE, I worked at Motorola, within their advanced process and research center as a Device and Spice characterization engineer for 5 years. I then moved to the EDA industry and have been happily working there for 12 years in the AMS domain. I have multiple technical publications under my belt and am currently the chair(wo)man for DesignCon Analog and Mixed Signal track. Why AMS? Because AMS is a fascinating environment with multiples aspects and challenges that evolve extremely quickly, where you keep redefining solutions and pushing the limits. Now about me, I could say I am French, that I like wine and eat cheese but that would be a little cliché, wouldn’t it? Let’s just say that I am active, that I like to be challenged in life and in sports and that I have a passion for swimming.

From my previous post (dated in June, I know, my blogging frequency could be higher:)), you may have noticed that we focus this year’s event to be performance, highlighting through customer presentations how Synopsys circuit simulation tools’ superior performance address mixed-signal design challenges of today and tomorrow.
We had a very successful event with a large audience and speakers from TSMC, Altera, Xilinx and ST.
Well, it is your lucky day, the videolog is now available
You can preview our videolog at:
In summary, our panelists gave very strong endorsements, highlighting the superior performance and multi-core scalability of our circuit simulation tools.
Below are the highlights of the talks:
TSMC speaker highlighted how SRAM designs at 16nm/10nm FinFET nodes require simulations on multiple process corners, have tighter accuracy requirements with significantly more RC parasitics. With latest enhancements in CustomSim, TSMC speaker described how they are able to meet the performance and accuracy requirement while maintaining their aggressive timelines.
Altera speaker shared how, through extensive benchmarking, they selected FineSim SPICE over competition due to its single-core performance and multi-core scalability. The speaker shared benchmark data showing FineSim SPICE was on average 2X faster than competition, and endorsed FineSim SPICE as the key ingredient in meeting project schedules for advanced node designs.
Xilinx speaker described how VCS AMS enables them to extend UVM-based digital verification and Real Number models to mixed-signal verification with CustomSim & VCS co-Simulation flow. The speaker endorsed VCS AMS as the fastest mixed-signal simulation solution on the market with better accuracy and easier setup/debug flow.
ST Micro speaker’s talk was focused on how they use CustomSim and VCS AMS for their Smart Power AMS verification for BCD process technology. Key takeaways were that CustomSim and VCS AMS are ST’s reference FastSPICE and mixed-signal simulation solution with superior performance. The speaker endorsed the new BCD optimizations in CustomSim and showed 2X faster results using the latest release of CustomSim.
Great event ! Thanks to our speakers and hope to see you next year. Feel free to contact me anytime if you have any questions.

VCS AMS is doing really well. After a successful webinar with ST and ARM and the release of a white paper, we are continuing our momentum with a tutorial at DVCON Europe on Tuesday, October 14th:
This highly technical tutorial will presents how the VCS AMS mixed-signal verification solution provides superior performance and flexibility. It was developed around best-in-class methodologies to extend proven digital verification techniques into mixed-signal designs. VCS AMS encompasses, but is not restricted to, capabilities for time efficient simulations using “Save and Restore” technology, aligned with the SV1800 industry standard syntax for “SystemVerilog nettype” constructs, represented as a holistic methodology within AMS Testbench that is underpinned by extremely successful UVM library.
The breadth and depth of usage of the individual portions within the solution are explained by real user case studies: extensive usage of VCS AMS Save and Restore for boosting productivity by STMicroelectronics and performance-driven VCS AMS behavioral modeling flow by Micronas.
So yes, you will miss Octoberfest but you get to attend an amazing webinar

DAC is here and we are ready!
You may have seen at SNUG that we announced VCS AMS, Synopsys advanced mixed-signal verification initiative to enable faster regression testing of Mixed-Signal SoCs.
We therefore decided to focus our DAC AMS luncheon technical event on VCS AMS. As a result, we have a very impressive panel of industry experts composed of AMD, Infineon, Micronas and STMicroelectronics. They will share their experiences and methodologies and highlight VCS AMS as the best mixed-signal verification tool available for today and tomorrow SoC designs (not my words, they did tell us without any torture or bribes :)).
Our speakers are (in chronological order):
Micronas : “Verification of Analog-on-Top Mixed-Signal ICs”
Infineon: “Power Aware Mixed-signal SoC Verification using VCS AMS”
AMD: “Exhaustive Verification OF Mixed-signal Designs using VCS AMS”
