PLANO, TX, May 18, 2026 – Siemens has released Solido Characterizer, an AI-assisted EDA software tool that reduces SPICE-based Liberty file generation from weeks to days across mature and advanced semiconductor process nodes.
The software is a developmental upgradation in Solido Characterization Suite software. It targets foundries and in-house chip design teams working with higher process complexity, tighter electrical margins, larger corner counts and emerging formats such as LVF.
Solido Characterizer uses predictive AI methods to generate SPICE-based Liberty files for semiconductor libraries. The software provides 7x greater throughput through two technical components. A faster AI engine supports Liberty generation for multi-PVT creation and LVF techniques, providing a 5x speedup. Solido LibSPICE, a purpose-built AI-accelerated characterization simulator, adds more than 2x performance improvement.
The software also connects with other Siemens EDA tools in the characterization flow. Solido Analytics checks characterization results, monitors resources during active runs and manages reruns. Solido Generator uses baseline Liberty files from Characterizer to train AI models that generate additional library views without SPICE simulation. Solido Characterizer can also work with Solido Fuse, built on the Fuse EDA AI system, to support generative and agentic AI workflows across characterization tasks.
“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 must complete characterization under tighter schedule and accuracy requirements. New process technologies add complexity through narrower electrical margins and higher corner counts, increasing the workload for each characterization run. Solido Characterizer addresses these requirements through:
- High-performance compute acceleration: Solido Characterizer reduces characterization time and supports accuracy requirements for complex chip designs across multiple process nodes
- Complex data formats handling: Emerging formats such as LVF require characterizers that can process large datasets with consistent runtime and data accuracy.
- Support for multiple teams and IP blocks: The software helps coordinate library generation across design teams, IP blocks and projects as model complexity increases.
- Live Liberty debugging for productivity: Solido Analytics integrates with Solido Characterizer to check characterization results, monitors active runs and manages reruns when issues appear
- Integration with Solido Custom IC solutions: The workflow covers SPICE simulation, variation-aware verification and IP validation.
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.”
