RPE dives deep into your design’s sequential behavior to unlock substantial, previously unapproachable power reductions.
Proprietary Deep Reachability Analysis Algorithm
Unique engine performs exhaustive reachability analysis across the flip flop and cone paths to enable clock gating on many logic levels and clock cycles, overcoming the limitations of standard heuristics.
Targeted Exploration & Guidance
Empowers designers by clearly highlighting specific, high-impact gating opportunities and providing actionable insights to guide the implementation of individual changes.
Other Features
• Advanced tools and suggestions for power saving
• Advanced clock trees and reset memory optimizations
• Visualize optimization opportunities
Agentic Power Exploration
Autonomous, RPE-assisted RTL power optimization: from months to hours. Zettabolt's Agentic Power Exploration pairs the RPE engine with AI agents that act as virtual designers. RPE finds and verifies the savings, and the agents apply them to your RTL.
The problem: power cleanup doesn't scale by hand
To optimize RTL power, designers load simulation data into a visualization tool, trace unnecessary toggling along data paths and manually pinpoint the registers and logic involved. Every change is manual, so the risk of functional errors is high, and the cycle repeats across the whole design. Power optimization can take months.
Optimizations using RPE
RPE scans the design, identifies key power-saving opportunities and generates detailed, actionable reports. It pre-verifies the suggested enable conditions, so designers can apply them with confidence. It is dramatically faster and safer than manual exploration, though applying a large set of recommendations by hand can still take days.
Why LLMs alone fall short
LLMs have broad knowledge but no built-in EDA engines to simulate, synthesize or measure. On their own they can't parse massive simulation data, project power savings accurately or guarantee functional correctness, and an unguided change can add bugs or even increase power.
Zettabolt Agentic Power Exploration: RPE + AI agents
RPE explores the design, identifies gating opportunities (clock, data, memory and sequential gating) and validates them to guarantee power savings. Using these pre-verified insights, AI agents make the RTL changes automatically. The fully automated workflow cuts optimization time, speeds up tape-out schedules and eliminates functional errors introduced by humans or LLMs.
Traditional flow
Agentic RPE flow
Four approaches, one clear winner
| Criteria | Traditional manual | RPE-assisted manual | LLM-only | Zettabolt Agentic |
|---|---|---|---|---|
| Time to close power | Weeks – months | Days | Hours (claimed) | Minutes – hours |
| Power savings verified? | No: trial & error | Yes, by RPE | No: unverified | Yes, by RPE, at every step |
| Functional risk | High | None | High | None |
| Designer effort | Very high | Medium | Low, but risky | Review only |
| Opportunity coverage | Limited by bandwidth | Full: RPE explores | Bounded by LLM knowledge | Full: explored & applied |
Why agentic wins
- RPE-verified at every step: no trial and error, no regressions
- Explores clock, memory, data and sequential gating across the full RTL
- Closed autonomous loop: explore → apply → validate → repeat
- Collapses months of manual effort into minutes or hours
- Removes the guesswork LLM-only flows can't resolve
- Engineers review outcomes; they don't hand-edit RTL
