Siemens today announced Solido™ Characterizer software, the next evolution in its Solido™ Characterization Suite software, designed to meet the semiconductor industry’s rapidly evolving requirements for speed, accuracy and efficiency in library characterization across process nodes, from mature to the most advanced.
Developed for foundries and in‑house chip design teams, Solido Characterizer uses advanced predictive AI technologies to accelerate and improve the creation of SPICE-based Liberty files, addressing the growing complexity of new processes, tighter margins, more corners and emerging formats such as LVF.
Solido Characterizer delivers 7x greater throughput, cutting Liberty file generation from weeks to days, through two complementary innovations. Its faster AI engine drives Liberty generation for multi-PVT creation and advanced LVF techniques to achieve a 5x speedup. The industry’s first purpose-built AI-accelerated characterization simulator, Solido LibSPICE, adds a further 2x+ performance boost. Together, these help ensure libraries are ready for any process node without delaying schedules or compromising data quality.
With demand for high-quality, production ready libraries rising across the semiconductor industry, Solido Characterizer enables teams to scale characterization across multiple IPs and design groups without compromising accuracy or timeline predictability. Its integration with Solido Analytics provides engineers with real-time QA insights, progress monitoring, and automated rerun capabilities that greatly streamline workflows. Solido Characterizer works in tandem with Solido Generator, which uses the baseline Liberty files produced by Characterizer to train AI models that generate additional library views without SPICE simulation, dramatically speeding up turnaround time and completing the end-to-end library creation flow within Solido Characterization Suite. Solido Characterizer can also be combined with Solido Fuse, built on the Fuse™ EDA AI system, to enable generative and agentic AI workflows that empower engineers to work faster across the characterization workflow.
“AI is redefining what is achievable across every dimension of semiconductor design, and characterization is one of the most transformative opportunities,” said Amit Gupta, chief AI strategy officer, senior vice president and general manager, Siemens EDA, Siemens Digital Industries Software. “With Solido Characterizer, we are delivering intelligent automation that fundamentally changes the economics of library development, enabling our customers to achieve levels of speed and precision that were simply not possible before. This positions engineering teams across every process node to innovate with confidence as the demands of modern semiconductor design continue to grow.”
Key customer benefits
Semiconductor teams across all process nodes face growing pressure to deliver fast, accurate characterization. New process technologies are raising the bar further with tighter electrical margins and larger corner counts adding significant complexity to every characterization run. Solido Characterizer addresses these realities with:
- High-performance compute acceleration: Empowering customers with a competitive edge across all semiconductor nodes by reducing characterization time and improving accuracy, directly enabling faster time-to-market for complex, advanced designs.
- Complex data formats handling: Emerging formats such as LVF require robust characterizers that can process large, detailed datasets efficiently. Quick and precise characterization helps teams keep up with evolving modeling standards and avoids downstream bottlenecks.
- Scalable across multiple teams and IPs: Accelerated, accurate characterization supports large organizations with many design teams, enabling rapid delivery of production-ready libraries for diverse projects – even as libraries and models grow in complexity.
- Live Liberty debugging for productivity: Integration with Solido Analytics delivers real-time QA of characterizer results, alongside resource monitoring for in-progress runs and streamlined re-runs for enhanced productivity.
- Integration with Solido Custom IC solutions: Spanning SPICE simulation, variation-aware verification and IP validation, contributing directly to faster time-to-market for complex semiconductor design.
Solido Characterizer in use in the semiconductor industry
“Through Solido Characterization Suite, the GlobalFoundries team has been able to validate and create design margins and .libs of excellent quality. With Characterizer specifically, we were able to maintain production accuracy as correlated to SPICE models while enabling 20 to 30percent speedup within our internal flows,” said James Culp, fellow, Design Enablement, GlobalFoundries.
“Siemens’ Solido Characterizer’s adoption process was quick and straight-forward due to the tool’s user-friendly setup capabilities and Siemens’ highly responsive and strong support. We were able to deliver signoff-ready margins and liberty for multiple, high-profile customers and GF technologies.”
“Siemens’ EDA tools are critical to Anatrix success, with Solido Characterizer being a key enabler for characterization of our single event latch-up radiation-hardened digital gate library, helping us work efficiently and with confidence,” said Greg Pauls, president, Anatrix. “Silicon testing of our analog and mixed-signal IP has verified that post-layout parasitic simulations using Siemens’ EDA flow accurately predicted IP behavior, reinforcing our trust in the results, and supporting first-pass success.”
