03The problem
The model passed. The real system still disagrees.
The gap is physical. The information needed to explain it is spread across tools, measurements and teams.
Plays the example figure for this point.
Materials, boundaries and operating conditions can differ between the model and the bench.
Fig. 1Board X · rev BExample · not real data Thermal, power, signal and mechanical results need a common context before they can explain each other.
Fig. 2Board X · rev BExample · not real data A result moves to the next team. The assumptions, failed tests and reasons behind it need to move too.

Call record
What should the team test next?
Carry the assumptions and evidence into the handoff. An engineer reviews the possible causes and chooses the next measurement.
- Candidate cause
- Heatsink contact at U1
- Next measurement
- Re-seat H1, repeat the run
- Review owner
- Thermal lead

Questions engineers ask.
Our engineers already make good calls. Why PlexMesh?
They do, and the call stays with them. What slows it down is everything around it: evidence spread across tools, context lost at handoff, and the same failure resurfacing on the next board. PlexMesh brings that evidence together so teams converge on the right call sooner and keep what they learned.
Which problems does PlexMesh solve?
Five that repeat across hardware teams: simulation and bench results that disagree, evidence scattered across tools and formats, context lost at handoff, teams slow to sync on the same picture, and early failures that keep repeating because no one can reproduce them. PlexMesh puts Pixel, Physics and People in one context, so every gap is visible, shared and reusable.
What does each role get?
Engineers: the gap, its likely causes and the next measurement worth running, in one place. Team leads: assumptions, owners and open decisions that survive the handoff. Partners and suppliers: sharing ranges, deviations and context within an agreed scope, without handing over raw data. This direction is still being explored.
What can PlexMesh do today?
In our working demo on an illustrative AI server board, PlexMesh compares predictions with measurements across signal, power, thermal and mechanical, ranks the likely fixes, suggests the next measurement and carries the result through each role’s handoff. Board X on this site is an illustrative example, not a customer result. We walk through the full demo under NDA.
Does it replace our simulation and test tools?
No. PlexMesh works on top of the tools you already use, connecting their outputs with measurements and the context behind each call, from upstream design to downstream use.
Who makes the call?
An engineer. PlexMesh lays out the prediction, the measurement and the gap side by side, and records who decided the next step and why. Any automated help works under human approval.
How do we start?
Bring one engineering question where the measurement disagrees with the model, or where context gets lost between teams. We’ll scope the work around it together.
Discuss a projectHow can we get involved early?
If your team lives with these gaps and wants to help shape PlexMesh, tell us about one. We’ll explore an early collaboration together.
Who needs PlexMesh?
Hardware teams whose calls depend on more than one kind of physics and more than one team: signal, power, thermal and mechanical engineers, the leads who own the handoff, and partners upstream and downstream. Today we focus on AI server boards, where these gaps are costly.
What data do we bring, and which tools does it work with?
The outputs you already have: model and simulation results with their assumptions, bench or field measurements with their conditions, and who reviewed what. PlexMesh reads common exported files, so you don’t change tools; we confirm your specific tools and formats in a scoped session.
How do you protect confidential designs and data?
Before any data is shared, we work through your security requirements with you under NDA. Work starts only once they’re confirmed.
Who owns our data, and how is it used?
We agree ownership and data use with each team under NDA before any data is shared, so the terms are clear before work begins.
Do we have to sign records?
No. Signing is optional. A team can use it to record a review or acknowledge a handoff when its process requires that step.
What are you building now?
We keep expanding the files PlexMesh can read, building up a reusable record of gaps and fixes, and automating more of the legwork, with an engineer approving every step. Beyond boards, we’re exploring board-to-rack and other physical systems such as robotics and semiconductors.
