Verifying Power Intent in Analog and Mixed-Signal Designs Using Formal Methods

By msteam | 21 Feb 2019

Analog and Mixed-signal (AMS) designs are increasingly using active power management to minimize power consumption. Typical mixed-signal design uses several power domains and operate in a dozen or more power modes including multiple functional, standby and test modes. To save power, parts of design not active in a mode are shut down or may operate at reduced supply voltage when high performance is not required. These...

Take Advantage of Advancements in Real Number Modeling and Simulation

By msteam | 26 Feb 2018

Verification is the top challenge in mixed-signal design. Bringing analog and digital domains together into unified verification planning, simulating, and debugging is a challenging task for rapidly increasing size and complexity of mixed-signal designs. To more completely verify functionality and performance of a mixed-signal SoC and its AMS IP blocks used to build it, verification teams use simulations at transistor...

Integrating AMS IP in SoC Verification Just Got Easier

By msteam | 6 Feb 2018

Typically, analog designers verify their AMS IP in schematic driven, interactive environment, while SoC designers use a UVM SystemVerilog testbench ran from a command line. In our last MS blog, we talked about automation for reusing SystemVerilog testbench by analog designers in order to verify AMS IP in exactly same context as in its SoC integration, hence reducing surprises and unnecessary iterations. But, what about...

Automatically Reusing an SoC Testbench in AMS IP Verification

By msteam | 4 Jan 2018

The complexity and size of mixed-signal designs in wireless, power management, automotive, and other fast growing applications requires continued advancements in a mixed-signal verification methodology. An SoC, in these fast growing applications, incorporates a large number of analog and mixed-signal (AMS) blocks/IPs, some acquired from IP providers, some designed, often concurrently. AMS IP must be verified independently...

Five Reasons I'm Excited About Mixed-Signal Verification in 2015

By TheLowRoad | 3 Dec 2014

Key Findings : Many more design teams will be reaching the mixed-signal methodology tipping point in 2015. That means you need to have a (verification) plan, and measure and execute against it. As 2014 draws to a close, it is time to look ahead to the coming years and make a plan. While the macro view of the chip design world shows that is has been a mixed-signal world for a long time, it is has been primarily the...

Mixing It Up in Hardware (an Advantest Case Study in Faster Full-Chip Simulations)

By TheLowRoad | 19 Nov 2014

Key Findings: Advantest, in mixed-signal SoC design, sees 50X speedup, 25 day test reduced to 12 hours, dramatic test coverage increase. Trolling through the CDNLive archives, I discovered another gem. At the May 2013 CDNLive in Munich, Thomas Henkel and Henriette Ossoinig of Advantest presented a paper titled “Timing-accurate emulation of a mixed-signal SoC using Palladium XP”. Advantest makes advanced electronics...

The Elephant in the Room: Mixed-Signal Models

By TheLowRoad | 5 Nov 2014

Key Findings: Nearly 100% of SoCs are mixed-signal to some extent. Every one of these could benefit from the use of a metrics-driven unified verification methodology for mixed-signal (MD-UVM-MS), but the modeling step is the biggest hurdle to overcome. Without the magical models, the process breaks down for lack of performance, or holes in the chip verification. In the last installment of The Low Road , we were at...

How Can You Learn About Mixed-Signal Verification and Implementation Flows at Your Desk?

By SumeetAggarwal | 30 Apr 2014

The vast majority of SoCs today are advanced mixed-signal designs. The old mixed-signal world looked like an analog environment on the left bolted to a digital environment on the right. Depending on which engineering group was responsible for final assembly, one part would be treated as a black box and the two parts would be bolted together at the system-on-chip (SoC) level. But today's mixed-signal designs have multiple...
