Power Intent (UPF)
LiveAuthor and visualize UPF power intent - see your power domains instead of hand-writing brittle files.
Why it exists
UPF is written by hand, reviewed by eye, and debugged at integration - where a wrong isolation strategy or a missed level shifter becomes a silicon-threatening bug. Low-power static checking is locked behind enterprise licences.
VisUPF gives power intent a visual, checkable workflow: author UPF with structure instead of raw text, see domains, supplies and strategies rendered as a diagram, and run low-power static checks against your RTL before integration. Open source, and free to use.
What it does
Domains, supply networks, isolation and retention strategies as a live diagram - the review artifact and the source of truth are the same thing.
Check power intent against the RTL netlist structure early, catching missing isolation and domain-crossing issues before they reach signoff.
A fast desktop app. Your RTL and power intent never leave your machine.
VisUPF is open source - download it, run it, and inspect exactly what it does with your design data.
How it compares
Where this tool stands against the open-source path and the commercial incumbents - capability by capability.
| Capability | VisUPF | Hand-written UPF + scripts | Commercial low-power static tools |
|---|---|---|---|
| Authoring model | Visual + structured | Raw text by hand | Text + proprietary GUI |
| Power-domain visualization | Built in, live | None | Yes |
| Static low-power checks | Included | None | Yes, licence-gated |
| Cost to start | Free, open source | Free | Enterprise licence |
| Data residency | 100% local desktop app | Local | Licence server dependent |
