Virtuoso Liberate MX 

Memory Characterization

Virtuoso Liberate MX enables fast and accurate characterization of large embedded memories to create instance specific memory models for timing, power and noise.

Virtuoso Liberate MX Datasheet »

Virtuoso Liberate MX extends Cadence’s ultra-fast standard cell and I/O library characterization capabilities to cover larger macro blocks such as memory and custom cores. 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 patented “inside view” technology for optimizing characterization runtime, memories and cores 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 and noise.

  • Virtuoso Liberate MX uses both a full block view and partitioned sub-block views to characterize large macro blocks efficiently and accurately.
  • The full block view is used to characterize power and drive the creation of sub-block partitions.
  • Employs a unique “Dynamic Partitioning” technology for optimized runtime.
  • Performs independently accurate SPICE characterization runs on decomposed partitions.
