Transistor-Level Verification Returns


A few decades ago, all designers did transistor-level verification, but they were quite happy to say goodbye to it when standard cells provided isolation at the gate-level and libraries provided all of the detailed information required, such as timing. A few dedicated people continued to use the technology to provide those models and libraries and the most aggressive designs that wanted to stri... » read more

Do Circuits Whisper Or Shout?


Maximizing SoC performance and minimizing power is becoming a multi-layered and multi-company challenge that depends on everything from ecosystem feedback and interactions to micro-architectural decisions about whether analog circuits whisper or shout. What used to be a straightforward architectural tradeoff between performance and power has evolved into a much more diffuse and collaborativ... » read more

Abstraction: Necessary But Evil


Abstraction allows aspects of a design to be described in an executable form much earlier in the flow. But some abstractions are breaking down, and an increasing amount of lower-level information has to be brought upstream in order to provide estimates that are close enough to reality so informed decisions can be made. The value of abstractions in design cannot be overstated. High levels of ... » read more

Full AMS Design Flow For The IoT


By Nicolas Williams and Jeff Miller The pressure for a new generation of (analog/mixed-signal) AMS design capabilities has been accelerated by the sudden demand for Internet of Things (IoT). These inexpensive devices are used in an expanding array of scenarios on the edge of the network — thus the demand for an AMS design environment that is affordable and easy to use, but powerful enough ... » read more

Full-Flow Tool Suite For Both Custom Analog And Mixed-Signal Designs


The Tanner EDA AMS IC design flow offers a cohesive, integrated mixed-signal design suite that is ideally suited to IoT and project-based design with its extremely short cycle times and sensitivity to cost. Learn more about the Tanner AMS solution in this white paper. To read more, click here. » read more

Analog Evolves Into Mixed Signal


Predictions about the Internet of Things suggest this may be the new “Killer App,” something the semiconductor industry has long been looking for. Reinforcing the forecasts are television commercials from companies such as Cisco and GE touting the IoT’s impact on everything from jet engines to robots, capturing everyone’s imagination. New categories of products such as smartwatches will... » read more

Analog FastSpice Platform Full-Spectrum Sampled Periodic Noise Analysis


Many high-performance analog/mixed-signal ICs include track-and-hold circuits to sample analog signals at one or more discrete timepoints per period. Although track-and-hold circuits are periodic, traditional periodic noise (pnoise) analysis does not apply because it measures the device noise impact integrated over an entire period rather than at instantaneous time points within the target peri... » read more

Dedicated ASIC Design Is Now Cost-Effective


Current market and technology trends have increased the demand for mixed-signal ASICs. Smaller projects with modest design budgets are viable due to low cost design tools and easy access to flexible, mature IC processes. This is especially compelling for developing mixed-signal ASICs for cost-sensitive sensor applications for the Internet of things (IoT). This paper discusses how costs and risk... » read more

SoC Integration Headaches Grow


As the number of IP blocks grows, so do the headaches of integrating the various pieces and making sure they perform as planned within a prescribed power envelope. This is easier said than done, particularly at the most advanced process nodes. There are more blocks, more power domains, more states and use-model dependencies, and there is much more contention for memories. There are physical ... » read more

Analog’s Day Of Reckoning


The numbers being touted by the semiconductor industry for IoT edge devices are staggering. How they are going to be used, who will make them, or indeed who will make money from them are much less certain. The industry seems to be clear about the content of these devices. A small processor, some flash memory or possibly even some of the new memory technologies that are coming along, a radio ... » read more
