Cadence® Virtuoso® Liberate™ AMS mixed-signal characterization solution enables fast and accurate characterization of large mixed-signal macros to create instance-specific memory models for timing, power, and noise.
The Liberate AMS solution extends Cadence’s ultra-fast standard cell and I/O library characterization capabilities to cover large mixed-signal macro blocks such as phase-locked loops (PLLs), data converters (ADCs, DACs), SerDes, high-speed transceivers, and high-speed I/Os. Macro blocks require additional pre-analysis steps in order to make fast and accurate characterization feasible. Leveraging a network of distributed CPUs and utilizing the “hybrid partitioning” technology for optimizing characterization runtime, mixed-signal macros can be characterized quickly and easily with the same accuracy and methods as standard cells, including the generation of timing constraints and modeling of current source models for timing, power, and noise.

- Automates the creation of standard Liberty models for large mixed-signal macro blocks by automatically capturing the interaction between digital and analog paths to identify latches, flops, and other probe nodes
- Improved throughput comes from “hybrid partitioning” technology, comprised of a full-block view and partitioned sub-block views to characterize large macro blocks efficiently and accurately
- Full-block view is used to characterize power and drive the creation of sub-block partitions
- Integrated with Virtuoso Analog Design Environment, enabling the reuse of test-benches and existing setup to quickly move from circuit design validation into library generation
