Chips are still debugged by hand — connection by connection, tool by tool. Caesarea Labs is building the first EDA platform dedicated to post-silicon validation, starting with automated Circuit Edit design.
Whether you run a FIB lab, lead chip design, or build tools for the post-silicon world — we want to hear from you.
Explore piloting Circuit Edit Professional inside your lab.
Get early access to Circuit Edit Designer for your organization.
FIB manufacturers, EDA vendors and other post-silicon players — let's collaborate.
Caesarea Labs is built by engineers who've sat on both sides of the Circuit Edit table — inside chip design teams and inside the labs that debug their silicon.
Deep expertise in semiconductor post-silicon validation, paired with hands-on EDA software development. That combination — insider knowledge of the target segment and the engineering to actually automate it — is rare, and it's the reason Caesarea Labs exists.
Post-silicon validation domain expert with insider knowledge of the target segment.
Experienced EDA developer with deep software and ML/AI expertise.
Whether you're a lab, a chip design team, or a potential partner — we'd like to hear from you.

Chip validation happens in two stages. Pre-silicon has spent two decades absorbing advanced EDA software. Post-silicon hasn't — and as process nodes shrink, it's the stage that matters more, not less.
Post-silicon validation has quietly become one of the largest cost centers in chip development — without a dedicated software category to manage it.
Post-silicon validation now drives up cost and time-to-market, lets more bugs escape to production, and slows innovation across the industry — and the discipline most exposed to it, Circuit Edit, is under mounting pressure.
Radically smaller process geometries make physical access to the chip harder with every generation.
Emerging BPD/BSPDN designs trap the transistor layer between two wiring stacks, cutting Circuit Edit success rates from ~70% toward ~10–30%.
Circuit Edit design is still passed back and forth by hand between chip designer and lab — a process that can stretch into months.
Teams are leaning on DFT, firmware workarounds and smarter ATEs instead — pulling investment away from an already-niche discipline.
Caesarea Labs is building a full suite of products for every discipline inside post-silicon validation — the segment the rest of the EDA industry has left behind.
EDA companies don't have insider knowledge of the post-silicon validation segment. Chip developers don't have EDA expertise. Neither has focused on building software for it — until now.

The first step in realizing our vision: automating the entire Circuit Edit — chip rapid prototyping — workflow, starting with Circuit Edit design.
Combines pre-silicon simulation with post-silicon methods — optical debug, system validation and more — to trace a bug to a device or signal.
The design engineer's theory of what's wrong and how to fix it, expressed at the electrical schematic level.
Translates the hypothesis into a precise, layout-level design — specifying the exact connection points and metal layers a FIB operator needs to execute the fix. Historically manual, slow and error-prone; Caesarea Labs automates it end to end.
A FIB operator carries out the design on an engineering sample, etching, cutting and depositing metal to implement the fix on real silicon.
Circuit Edit design has always meant iterating manually between chip designer and lab. Caesarea Labs replaces that loop with an asynchronous, automated exchange.
Reaching an agreed-upon Circuit Edit takes rounds of back-and-forth: suggestions, questions about specific signals or cells, feasibility, complexity, timing. Each round is a chance for chip IP to leak. Automation replaces that open-ended exchange with a single, redacted, controlled channel.
Full-chip layout data is stored and processed only inside your own infrastructure — on-prem or private cloud.
Only the redacted subset of the layout needed for a specific edit is ever generated and shared with the lab.
Redacted data moves over a proprietary, multi-path routing mechanism that prevents reconstruction of the original layout.
Circuit Edit runs in more places than you'd think — from chipmakers' internal labs to specialist service providers and university research centers. Caesarea Labs fits wherever a FIB is running Circuit Edit.
Four types of organizations rely on Circuit Edit today — each with different constraints, and each a fit for Caesarea Labs.
Chipmakers with internal post-silicon validation labs — including dedicated Circuit Edit teams — running Circuit Edit as part of new product development.
Specialist labs offering Circuit Edit as a service to many different customers, rather than a single internal design team.
Institutions with at least one Circuit Edit-capable tool / universities and institutes with significant electronics, semiconductor, R&D, or tech-transfer departments.
Foundries relevant to Circuit Edit for prototyping and debug, as well as to automated mask repair, a related discipline built on the same FIB-based technology.
