Data grid & cleaning
Edit, sort, filter, group, transpose and de-duplicate. Mark and remove outliers, remove failing rows and add calculated columns.
Test data analysis for Windows
From raw test data to yield answers, in one desktop application.
Testalytix analyses and visualises semiconductor and measurement test data, with optional Python scripting and a Claude AI assistant. Built for test, yield, product and quality engineers working with wafer-test, final-test and qualification data.
Reads your data as it comes off the tester
- STDF (incl. .gz / .zip)
- CSV / TXT
- EDF
- Excel
- SQL Server
One data set, many tools
Load once. Every analysis works on the same data.
Open several files together and they are merged into one spreadsheet-like grid. Clean it there, and every statistic, chart and report follows.
Statistics tables
Count, mean, median, standard deviation, Cp/Cpk, %Fail and more, for all tests at once or per group such as lot or wafer.
Flexible limits
Load limits from a file, type them in, or calculate them: PAT-based or from a Cpk target.
Bin & yield analysis
Fail Pareto, Generate Bin1 and Retest Recovery, with the STDF hardware and software bin records at hand.
SQL Server workspace
Query your test database directly with a query builder and SQL editor, and analyse the result like any file.
Pre / post measurement
Compare rounds before and after stress, burn-in, rework or retest, device by device, to find new fails and parameter shifts.
Charts
Eight chart types, one double-click away.
Pick a chart type, double-click a test, and step through the test list with the arrow keys. Group by lot or wafer, zoom into a region to filter the data, and see the statistics of exactly what is plotted.
- Box plot
- Histogram
- Cumulative P%
- XY plot
- Temperature evaluation
- Wafer map (parametric & bin)
- Defect density
- Scatter plot
Advanced analysis
Find what drives the variation.
Go beyond single-test statistics with multivariate and measurement-system tools built into the same workflow.
- Correlation & drift
- XY correlation between tests and pre/post drift analysis.
- PCA & K-Means clustering
- Scree, scores, loadings and biplots; cluster profiles to spot device populations.
- Gauge R&R / MSA
- Separate measurement-system variation from part variation, prober to prober.
Reporting & re-use
Reports in the same window. Setups you can repeat.
The built-in report editor collects charts and statistics tables into a document you can save, export and print. A plot recipe stores a whole chart setup and re-applies it to the next lot in two clicks.
Report current, selected or by category
One plot, a list of ticked tests, or every test category in one run.
Full word-processor editor
Document tabs, spell checking, and print, draft, web and reading layouts.
Save as HTML
Share results with colleagues who do not have the application.
Plot recipes
Save a chart setup once and apply it to every new lot.
Python & Claude
Your own scripts. An AI assistant that knows your data.
When a calculation needs something no button offers, the Python page runs your own scripts on the loaded data, and the Claude chat helps you write them.
Python on the grid
Read the data grid into pandas, analyse it with numpy, scipy and the rest of the ecosystem, and send the result table back for charts and reports.
Uses your Python
Finds 64-bit Python 3.8+ installations, virtual environments and conda environments on the PC by itself.
Ask Claude about your data
Ask in your own words about your data, a plot or a wafer map. Claude answers, writes the Python script, and, when you ask, plots, reports, sorts and filters.
You stay in control
Runs with your own Anthropic API key, stored encrypted on your PC. The assistant is limited to Testalytix tools; sorting, filtering and several plot actions ask Yes / No first.
Built for long days of engineering work.
Sharp on any screen
Windows, fonts and icons adapt to each monitor's scaling, also when moved between monitors.
Clear feedback
Actions that cannot run explain why, and long operations show progress until they finish.
STDF records included
Test synopsis, master information, hardware and software bin tables alongside your data.
Full user manual
Every ribbon page, chart and analysis documented step by step, with built-in help.
