What is a .SPI file?
SPI is a SPICE netlist used to simulate an electronic circuit.
- Did you know
- SPICE simulation lets engineers test a circuit before building it.
- In 2011 the IEEE declared SPICE an official Milestone of electrical engineering, unveiling a plaque at Berkeley’s Cory Hall where it was written.
- A netlist names each component and the numbered nodes it connects, which the simulator turns into equations to solve.
- What Analyser reads
- Open scientific, medical and engineering files: DICOM scans, NIfTI brain volumes, Garmin FIT/TCX activities, FITS astronomy frames, FASTA/FASTQ sequences, chemistry structures (MOL/SDF/MOL2/CIF/XYZ), Gerber/Excellon PCB data, SPICE netlists, EDF/BDF biosignals, JCAMP-DX spectra, SPSS/Stata/SAS datasets and VTK/ParaView meshes - metadata extracted entirely in-browser.
- Depth of analysis
- .SPI is an identification-grade format: Analyser recognises it from its bytes and decodes the header metadata it carries, rather than opening it in a full viewer. Formats that do get a full viewer are marked "Full" on the formats page.
- Open a .SPI file
- Drag a .SPI file onto the Analyser home page (or tap to pick one). It is identified entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
