12-hour synthesis run. One bad change. Start over.
Timing closure takes all day. You tweak a constraint. It regresses. There's no rollback. You stare at the queue again. That's real money, not just time.
💸 $400+ compute per bad run
Instant rollback · EDA & FPGA Workflows
Your 12-hour
run just
broke.
deltapro checkpoints your entire project state — bitfiles, coverage DBs, regression outputs, test configs — and restores any of them instantly. 4 seconds. Single binary. No dependencies.

The real cost
You're burning cash
on failures you can't undo.
Every EDA, verification, and test automation engineer knows this. It's not a workflow problem — it's a money problem.

Backup folders that make you feel insane.
proj_v3_final_REAL/ — and you still can't find last Thursday. Manual copies eat disk and fail when you need them most.
⏱ 45 min hunting state per incident
Regressions that fail 7 hours in.
Your 10-hour regression hit a bad config at hour 7. You can't recover the 87% pass state. All that compute gone. Re-run from zero.
🔥 8h compute completely wasted
Test configs that drift between runs.
12 new testbenches added. Coverage dropped. Can't tell if it was config or tests — no diff, no rollback, no root cause.

Two engineers. One project. One disaster.
Bob overwrote Alice's overnight synthesis to "test something quick." 10-hour run gone. Management is asking about the tape-out date.
💣 Shared project corruption
"Reproduce the result from last month."
Client wants the exact state that produced your golden result. You have no idea which run. 3 days recreating it from memory and guesswork.

The fix
One command
before every
risky change.
deltapro snapshots your entire working state — bitfiles, outputs, configs, databases, reports. Everything that took compute to produce.
- → Save full project state in seconds before any risky operation
- → Restore any snapshot instantly — no recompute, no queue
- → Single self-contained binary: Linux, macOS, Windows WSL2
- → Content-dedup means 5 snapshots ≠ 5× disk space
- → Point --store-path at your NAS for team-shared rollback history
- → .ckptignore skips logs and temp caches automatically
- → TCL hook integration for Vivado, Quartus, Genus, VCS and more

Who uses deltapro
Every workflow that runs
on expensive compute.
Anywhere a failed run costs hours and money, deltapro pays for itself on day one.
FPGA / Synthesis
Timing closure in 8h. Roll back in 4s.
Save state the moment you hit timing. Experiment freely. If anything regresses, you're back to the golden state in under 5 seconds — no queue, no rebuild.
Save before every constraint tweak
Tag and name golden states
Diff any two snapshots instantly
Verification Engineer
78% coverage. Snapshot it. Prove you hit 93%.
Checkpoint your exact coverage database before new tests. Run the diff afterward. Irrefutable proof of improvement — and a rollback if things break.
Checkpoint coverage milestones
Diff coverage DBs across runs
Auto-save via TCL hooks
Regression Builder
87% pass rate at hour 6. Don't lose it.
Checkpoint mid-regression. If your suite hits a bad config late in the run, restore to the last known-good state and investigate without rerunning from scratch.
Mid-run snapshots via scripting
Restore to last known-good instantly
Compare pass states across builds
Test Infrastructure
Config drift is killing your pass rate.
Snapshot before each batch. When results go sideways, diff the configs to find exactly what changed — then roll back in one command.
Snapshot before every config change

★★★★★
"Hit timing at 480MHz after 9 hours. Saved the checkpoint. Tweaked aggressively. Timing failed at hour 2. Restored in 4 seconds. Saved me an entire day. Insane value for $39."
★★★★★
"We had a regression at 87% pass at hour 6. Config went sideways. Before deltapro, that was a full rerun. Now we restore the last good state instantly. Already paid for itself 10× over."
★★★★★
"Client called asking to go back to the synthesis state from last Tuesday. I did it live on the call in 4 seconds. They were floored. I looked like a magician. Absolutely worth every dollar."

FAQ
Common questions
- What is deltapro?
- deltapro is a single-binary checkpoint and rollback tool for EDA and FPGA workflows. It snapshots your entire project state — bitfiles, coverage databases, regression outputs, test configs — and lets you restore any checkpoint in under 4 seconds, eliminating the need to rerun expensive synthesis or verification jobs.
- How does deltapro save compute costs?
- By letting you roll back to any previous project state in 4 seconds instead of rerunning a 12+ hour synthesis or verification job, deltapro saves an average of 30% on compute costs. A single recovered run typically saves hundreds of dollars in cloud or on-prem compute charges.
- What platforms does deltapro support?
- deltapro ships as a self-contained single binary with zero dependencies. It supports RHEL 7+, Ubuntu 18+, macOS 12+, and Windows WSL2.
- Does deltapro work with Vivado, Quartus, and other EDA tools?
- Yes. deltapro is tool-agnostic and works by snapshotting files in your project directory. It integrates with any EDA tool including Vivado, Quartus, Genus, Innovus, and VCS via simple shell or TCL hooks.
- How much does deltapro cost?
- deltapro is a one-time purchase of $39. It includes a 14-day no-questions refund guarantee, instant download after payment, and a single binary that works across all supported platforms.
- How does deltapro handle disk space with many snapshots?
- deltapro uses content-addressed deduplication, meaning unchanged files are stored only once across all snapshots. This typically reduces disk usage by 80% compared to naive file copies. A .ckptignore file lets you automatically skip logs and temporary caches.
