The st9 file extension is associated with SPICE (Simulation Program with Integrated Circuit Emphasis), software developed by National Instruments Corporation.
An st9 file is a status file used by SPICE to store information about the software. It is a supporting file for the SPICE environment rather than a standalone document intended for general use.
This format is associated with the Microsoft Windows version of SPICE. The file is normally created and maintained by the software when required.
Open an st9 file with the Microsoft Windows version of SPICE, the software associated with this format. In most cases, the file is intended to be read automatically by SPICE rather than opened manually.
Because it is a software status file, a text editor may not display useful information or may show incomplete internal data.
An st9 file is a supporting status file, so it normally has no meaningful conversion to another format. Keep it with the related SPICE files and let SPICE manage it.
