Library Characterization Tidbits: Exploring Intuitive Means to Characterize Large Mixed-Signal Blocks

Hello again! I'm back with another interesting topic in the Library Characterization Tidbits blog series.

In the last blog of this series, Over the Clouds and Beyond with Arm-Based Graviton and Cadence Liberate Trio, Seena Shankar shared how the Cadence^® Liberate^TM Trio Characterization Suite, Arm-based Graviton Processors, and Amazon Web Services (AWS) Cloud have joined forces to cater to the High-Performance Computing, Machine Learning/Artificial Intelligence, and Big Data Analytics sectors. 

This time, let's review a key characteristic feature of Cadence Liberate AMS Mixed-Signal Characterization that offers to you ‘ease of use’ along with many other benefits like automation of standard Liberty model creation and improvement of up to 20X throughput.

The Liberate AMS characterization solution is industry’s first digital implementation and signoff flow to achieve “Fit for Purpose - Tool Confidence Level 1 (TCL1)” certification. It enables you to meet stringent ISO 26262 automotive safety requirements.

We all know how important ‘ease of use’ is when SoCs are getting more complex to meet the industry’s demands and when there is more IP reuse in Digital-on-Top (DoT) design flows for SoC signoff with static analysis tools. In such scenarios, creation of Liberty library representations needed for large mixed-signal blocks is another big challenge.

To deal with challenges like these, our experts have integrated the Liberate AMS characterization solution into the graphical user interface-driven Virtuoso ADE Assembler—a tool that most custom circuit designers are familiar with. This seamlessly integrated solution is accessible through the Liberate AMS Setup form available in Virtuoso ADE Assembler. You can therefore leverage the ADE testbenches and setup to quickly move from circuit design to library generation. Imagine the kind of enhanced usability and productivity this integrated solution offers without requiring an in-depth knowledge of characterization and Liberate AMS!
