Silica
The reasoning layer for chip verification.
AI-powered verification automation for semiconductor debugging.
Turning days of manual debugging into minutes of automated analysis.
Chip verification debugging is slow and manual.
When tests fail, engineers sift through logs, waveforms, and specs to find root cause. Verification consumes 50-70% of engineering effort—and outcomes still depend on tribal knowledge and manual investigation.
Manual Workflows
Log parsing, waveform inspection, and ad-hoc tooling. Engineers stitch together artifacts by hand with little cross-artifact reasoning.
Time-Consuming Debug
Hours to days per failure. GB-scale simulation logs and waveforms make it impossible to find root cause quickly at scale.
Unpredictable Outcomes
Results depend on senior engineer experience and hard-coded heuristics. Debug cycles stretch timelines and create schedule risk.
AI diagnostic reasoning for chip verification.
Silica reasons across logs, waveforms, and RTL to identify root cause, trace failures back through the design, highlight the signals that matter, and deliver recommended fixes—compressing days of debugging into minutes.

Purpose-built for verification engineers.
Log Analysis
Stream and parse GB-scale UVM logs. Cluster errors, correlate events, and map causal relationships across test runs.
Waveform Anomaly Detection
Detect signal anomalies, flag X/Z states and metastability hints, and check timing and protocol windows automatically.
RTL Root-Cause Tracing
Parse module hierarchy and signal drivers. Extract FSM states and clock domains to trace failures back to implicated modules.
Spec-to-Assertion Generation
Convert natural-language specs into structured, testable behaviors and generate SystemVerilog assertions (SVA).
Debug Knowledge Base
A growing repository of verification patterns. Each captures symptom, root cause, and resolution — improving with every regression.
