What is a .SP file?
SP is a SPICE netlist listing components and connections for circuit simulation.
- Did you know
- A SPICE netlist describes a circuit as a list of parts and the nodes joining them.
- Laurence Nagel wrote the original SPICE as a Berkeley graduate student under professor Donald Pederson, who insisted the simulator be given away freely.
- The original SPICE was written in FORTRAN and released into the public domain, seeding countless commercial simulators.
- 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
- .SP 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 .SP file
- Drag a .SP 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.
