• Hybrid TTL/CMOS models (for 74HCT series).
• Fault injection models (for teaching failure analysis).
• A plugin for KiCad’s simulation engine.

• Adaptive TTLs: She proposes dynamic TTLs that adjust based on observed read/write patterns, update frequency, and system load, rather than static values set by heuristics.
• Probabilistic freshness models: Ortega applies probabilistic models to quantify the likelihood that cached data remains fresh, enabling operators to make risk-informed TTL choices.
• Cost-freshness trade-off analysis: Her frameworks formalize the trade-off between increased fetch costs (and latency) from lower TTLs and the staleness risks of longer TTLs, often using expected-cost minimization.
• Multi-layer coordination: Recognizing modern stacks use multiple caching layers (client, CDN, edge, origin), she emphasizes coordinated TTL policies to avoid oscillations and cache stampedes.
