stdf-convert
Read STDF V4 and V4-2007 semiconductor test data files, and convert them to JSON Lines.
Parsing is done in Rust by rust-stdf.
import stdf_convert
for record in stdf_convert.records("results.stdf.gz", ["PIR", "PTR", "PRR"]):
print(record["record_type"], record["data"])
stdf_convert.convert("results.stdf.gz") # writes results.jsonl
Installing the package also installs the stdf-convert command (stdf-convert --help), or
run it without installing: uvx stdf-convert results.stdf.
Each record is a dictionary:
{
"sequence_number": 42, # position in the file (unaffected by filtering)
"byte_offset": 1234, # offset of the record header in the decompressed stream
"rec_typ": 15,
"rec_sub": 10,
"record_type": "PTR",
"data": {"TEST_NUM": 1001, "HEAD_NUM": 1, "SITE_NUM": 0, "TEST_FLG": b"\x00", "RESULT": 0.018, ...},
}
Numbers are int or float (including NaN and infinities), byte and bit fields are
bytes, and absent optional fields are None. Gzip (.gz), bzip2 (.bz2) and zip
(.zip, first member) files are read directly. Errors raise stdf_convert.StdfError;
an unknown record type in a filter raises ValueError.
In the JSON Lines output, byte and bit fields are lowercase hex strings ("TEST_FLG":"80")
and NaN and infinities are the strings "NaN", "Infinity" and "-Infinity", so every
JSON parser can read the file.
