The st2 file extension is associated with SPICE (Simulation Program with Integrated Circuit Emphasis), originally developed at the Electronics Research Laboratory of the University of California.
SPICE uses the file to store status information related to its circuit simulation work. It is an auxiliary file belonging to the SPICE software rather than a standalone document or simulation design.
Open an st2 file with the Windows version of SPICE that created it. Because it is an auxiliary status file, it is normally used by the program itself rather than opened as a document.
An st2 file does not normally have a useful standalone conversion. Use SPICE to access the associated simulation and export any required results in a format supported by that program.
