ML Characterization Suite

Fast, Accurate Library Characterization Tools Powered by Machine Learning

Standard cell, memory, and I/O characterization is time- and resource-intensive, taking hundreds or thousands of CPUs and SPICE licenses, and running for weeks or months for a single iteration. Solido ML Characterization Suite significantly reduces standard cell, memory, and I/O  characterization time and resources, while delivering production-accurate Liberty models. ML Characterization Suite is proven in production customer environments, and compatible with all characterization flows.


Reduces library characterization time by 30 to 70%

Solido ML Characterization Suite Predictor uses machine learning to accelerate characterization of standard cells, memory, and I/O. Predictor accurately generates Liberty models at new conditions from existing Liberty data at different PVT conditions, Vt families, supplies, channel lengths, model revisions, and more. It significantly reduces up-front characterization time as well as turnaround to generate library models, and works with NLDM, CCS, CCSN, waveforms, ECSM, AOCV, LVF, and more.

Statistical Characterizer

Generates Monte Carlo accurate statistical timing models, >1000x faster than Monte Carlo

Solido ML Characterization Suite Statistical Characterizer uses machine learning technology to accelerate statistical characterization of standard cells, memory, and I/O. It delivers true 3-sigma LVF/AOCV/POCV values with Monte Carlo and SPICE accuracy, and handles non-Gaussian distributions. It adaptively selects simulations to meet accuracy requirements, minimizing runtime for all cells, corners, arcs, and slew-load combinations.

For fast, accurate, statistical characterization, Statistical Characterizer and Predictor can be used in combination. Use Statistical Characterizer on anchor corners to quickly add Monte Carlo accurate LVF, and then use Predictor to create and expand remaining corners, including statistical characterization data, generating savings of more than 50% without compromising accuracy.
