STDF Reader Skill
This skill provides access to the STDF Reader CLI tool for parsing and analyzing semiconductor STDF test data files.
Prerequisites
Install via pip (python version 3.9+):
pip install stdf-reader
Use the virtual environment for running any commands:
source .venv/bin/activate
Available Commands
1. Convert STDF to CSV (most common)
Parse one or more STDF files into a CSV log for analysis:
stdf-reader convert-csv [-o output_name]
Options:
--ignore-tnum β Ignore test number (match by name only)--ignore-chnum β Ignore channel number in test name--no-merge β Output separate CSV per file (default: merge into one)Example:
stdf-reader convert-csv input.stdf
Output: input.stdf_csv_log.csv
stdf-reader convert-csv lot1.stdf lot2.stdf -o merged_output
Output: merged_output_csv_log.csv
2. Convert STDF to XLSX
Parse STDF file into a formatted Excel table (shows all record types):
stdf-reader convert-xlsx
3. Convert Diagnosis STDF to ASCII
Convert STDF V4-2007.1 files with STR/PSR diagnosis records to ASCII CSV:
stdf-reader convert-diag
4. Extract Single Record Type
Extract a specific STDF record type (DTR, GDR, TSR) to CSV:
stdf-reader extract-record --type DTR
5. Generate Analysis Report
Generate comprehensive XLSX report from CSV (includes data statistics, bin summary, wafer map):
stdf-reader report [-o output.xlsx]
6. Generate Correlation Report
Compare means across 2+ STDF files merged in a single CSV:
stdf-reader correlation [-o output.xlsx]
7. Generate Site-to-Site Correlation
Compare test data across different test sites:
stdf-reader s2s [-o output.xlsx] [--cherry-pick "1,3,5"]
Options:
--cherry-pick "1,3,5" β Site numbers to pick, comma-separated8. Generate PDF Charts
Generate PDF with trendline + histogram charts for selected tests:
# By regex pattern
stdf-reader pdf --regex "IDD.*"All tests
stdf-reader pdf --allSpecific tests
stdf-reader pdf --tests "210 - IDD_Static <> curr"
Options:
--no-limits β Don't plot failure limit lines--group-by-file β Group trends by file instead of by site9. Extract Sub-CSV
Extract only specific tests from a CSV file:
stdf-reader extract-tests --regex "VDD.*"
10. List Tests
List all test instances in a CSV file:
stdf-reader list-tests
stdf-reader list-tests --filter "IDD.*"
11. Transpose CSV
Swap rows and columns in a CSV file:
stdf-reader transpose
Typical Workflow
1. Convert STDF to CSV: convert-csv input.stdf
2. List available tests: list-tests input.stdf_csv_log.csv
3. Report: report input.stdf_csv_log.csv
4. PDF charts: pdf input.stdf_csv_log.csv --regex "pattern"
Output File Naming
convert-csv β {input}_csv_log.csvconvert-xlsx β {input}_excel.xlsxconvert-diag β {input}_diag_log.csvextract-record β {input}_{TYPE}_Rec.csvreport β {base}_analysis_report_{timestamp}.xlsxcorrelation β {base}_correlation_report_{timestamp}.xlsxs2s β {base}_s2s_correlation_table{timestamp}.xlsxpdf β {input}_results.pdfAll outputs default to the same directory as the input unless -o is specified.
βοΈ Configuration
