Spec-accurate answers from every data sheet, errata sheet, and app note
DaaX LAKEer builds a DaaX 3D Graph of your parts, parameters, test conditions, and design guidance, then answers questions across your entire documentation library with a source for every claim.
Seeing is believing. Our live demo has more than 80 real power-device data sheets and application notes already ingested. Ask it anything, right now, with no signup.
The technical truth about every part, available to everyone who needs it
The answer to almost every question a semiconductor company gets is already written down. It is in a data sheet parameter table, an errata sheet for a specific silicon revision, a qualification report, a failure analysis report from three years ago, or an FAE's Teams thread. The challenge is finding it quickly and getting it exactly right.
FAEs, application engineers, quality engineers, and design teams spend hours opening PDFs one at a time. General-purpose AI assistants are faster, but a spec pulled from the wrong column, the wrong temperature condition, or a superseded errata sheet is worse than no answer at all.
LAKEer changes the job from keyword-searching individual PDFs to asking questions across the whole library at once, and getting answers your engineers can verify in seconds.
Don't take our word for it — ask the demo yourself
Reading about grounded answers is one thing. Watching one come back with the data sheet page it came from is another. That is why the semiconductor demo is open to everyone, with nothing to install and no account to create.
What's in it: more than 80 data sheets and application notes for Mitsubishi Electric power devices — all publicly available documents — containing text, parameter tables with merged cells, and figures. Ask about any one of them, or all of them at once.
Example queries to start with
- "What is the collector-emitter saturation voltage for the CM450DX-24T?" A parameter buried in a merged-cell table, returned with the page it came from.
- "What is the isolation voltage rating for the CM300DX-24T?" The same class of question against a different part, across the whole library.
- "What does the 3rd digit in the date code mean?" The kind of question customer support fields every week, answered from the documentation rather than from memory.
- Ask that last one in Japanese or Korean and get the same answer from the same English-language documents.
Bring your own question as well. The source documents are public, so you can open them and check the answer against the original — which is exactly the point.
Example use cases across the semiconductor business
From the first design-in conversation to the last customer return, LAKEer answers the questions your teams ask every day.
| Use case | Ask LAKEer | What makes the answer trustworthy |
|---|---|---|
| Design-in and pre-sales | ||
| Parametric product searchFAEs, AEs, design engineers | "What is the collector-emitter saturation voltage for the CM450DX-24T?" | Each value in the DaaX 3D Graph stays connected to its part, parameter, and test conditions, so a typical value at 25 °C is not returned as a maximum over temperature. Values are stored as numbers, not text. |
| Competitive cross-reference and second-sourcingFAEs, sales, supply chain | "What's our closest replacement for this competitor's product?" | LAKEer compares the two data sheets parameter by parameter. In grounded mode it reports package and pinout differences it finds in the documents instead of assuming a drop-in fit. |
| RFQ and customer requirements complianceAEs, sales engineers | "Check this customer requirements spec against our part's data sheet and list any requirement we don't meet." | Complex query decomposition splits the RFQ into individual requirements. Each result is cited to the data sheet page and table it came from. |

| Errata and silicon revision impactFAEs, customer support, firmware engineers | "Does any errata item affect SPI in DMA mode on rev B silicon?" | LAKEer connects the errata sheet, data sheet, and app note that mention the same peripheral and silicon revision. Automatic Sync removes superseded errata from future answers. |
| Failure analysisQuality and FA engineers | "Have we seen EOS failures on this pin in automotive returns before, and what was the root cause?" | LAKEer searches past FA and 8D reports along with the email and Teams/Slack threads where root causes were discussed, and shows the source for each finding. |

FAEs, AEs, design engineers
"What is the collector-emitter saturation voltage for the CM450DX-24T?"
Each value in the DaaX 3D Graph stays connected to its part, parameter, and test conditions, so a typical value at 25 °C is not returned as a maximum over temperature. Values are stored as numbers, not text.
Competitive cross-reference and second-sourcing
FAEs, sales, supply chain
"What's our closest replacement for this competitor's product?"
LAKEer compares the two data sheets parameter by parameter. In grounded mode it reports package and pinout differences it finds in the documents instead of assuming a drop-in fit.
RFQ and customer requirements compliance
AEs, sales engineers
"Check this customer requirements spec against our part's data sheet and list any requirement we don't meet."
Complex query decomposition splits the RFQ into individual requirements. Each result is cited to the data sheet page and table it came from.
Quality, reliability, and post-sales
Errata and silicon revision impact
FAEs, customer support, firmware engineers
"Does any errata item affect SPI in DMA mode on rev B silicon?"
LAKEer connects the errata sheet, data sheet, and app note that mention the same peripheral and silicon revision. Automatic Sync removes superseded errata from future answers.
Failure analysis
Quality and FA engineers
"Have we seen EOS failures on this pin in automotive returns before, and what was the root cause?"
LAKEer searches past FA and 8D reports along with the email and Teams/Slack threads where root causes were discussed, and shows the source for each finding.
Customer quality questionnaires
Quality, sales operations
"What are the AEC-Q100 grade and MSL rating for this part, and where is that documented?"
Grounded mode requires every claim to trace to a specific passage. The audit trail shows the document and page for each answer, ready to attach to the questionnaire.
Internal engineering and operations
Documentation consistency audit
Technical publications, product engineering
"Do the data sheet, app note, and selection guide list different absolute maximum ratings for the same part?"
Because specs are stored as numbers tied to specific parts, LAKEer compares them across documents and flags the ones that disagree, with a citation to each.
Foundry PDK and third-party IP documentation
IC design and verification teams
"What reference clock requirements does the SerDes IP integration guide specify for our target data rate?"
Single-tenant deployment keeps NDA documents isolated. The Company Language Cartridge maps internal project codenames to the IP and process names used in vendor documents.
Combined structured and unstructured search
Search databases and documents in one question
FAEs, sales, supply chain
"Which parts meet these specs and are in stock, and what does the app note recommend for their layout?"
DaaX SQLer answers the inventory and parametric part from your database; DaaX LAKEer answers the layout guidance from your app notes. One answer, with sources for both.
Several of these questions run against the live demo today. The design-in rows use the public power-device library in the semiconductor demo, and the email and Teams/Slack search behind the failure analysis row has its own demo on the same page.
Advantages of LAKEer for spec-sensitive answers
Semiconductor documentation is where ordinary retrieval-augmented generation (RAG) breaks down. A vector index finds text that reads like the question; it cannot tell a typical value from a maximum, a 25 °C condition from a full-temperature-range condition, or the current errata sheet from the one it replaced. LAKEer's neuro-symbolic AI engine gives the LLM a helping hand with structure, verified evidence, and your company's own vocabulary.
Test conditions stay attached to every spec
In the DaaX 3D Graph, a value is connected to its part, parameter, and conditions, and to whether it is a minimum, typical, or maximum. Questions about a specific condition get the value measured under that condition.
Tables treated as tables
Parameter tables with merged cells are stored as structured data, and numeric values are stored as true numbers. That makes threshold searches and cross-part comparisons a calculation, not a guess from text.
ClaimGuard verifies before you see the answer
ClaimGuard breaks every generated answer into individual claims and checks each one against the retrieved evidence. Claims that fail are corrected or regenerated. When the evidence isn't there, LAKEer says so.
Grounded mode for compliance-grade answers
For RFQs, quality questionnaires, and spec lookups, grounded mode requires every claim to trace to a specific passage, with no extrapolation. Knowledge mode is available for open-ended and comparative questions.
Always the current revision
Automatic Sync detects new, changed, and deleted documents and updates the 3D Graph, vector index, and tables together. When a data sheet is revised or an errata sheet is superseded, answers reflect the current version.
Understands your part numbers and codenames
Teach LAKEer your internal project codenames, die names, base part numbers, and orderable suffixes once with a Company Language Cartridge. It is built on SKOS, the W3C standard for controlled vocabularies, so the vocabulary you build is portable to any SKOS-aware system.
An audit trail on every answer
Every answer shows the exact document, page, and table each part came from, so an FAE can forward a verified answer to a customer with confidence.
Built for how semiconductor companies work
See it, then see it on your own documents
Start with the public demo — and scroll the same page for an email and Teams/Slack demo and a 200-page oil well report if you want to see how far the same engine goes. When you want the same answers from your own data sheets, errata, FA reports, and app notes, we can have a conversation about that.
