SPICE AC/frequency-domain output
File type: Various data file
Files with ac6 file extension contain AC/frequency-domain output generated by SPICE simulation software.
The output records results from an AC analysis, such as circuit behavior measured across a range of frequencies.
Found 2 different file type records with the same ac6 filename suffix.

The ac6 file extension is associated with SPICE (Simulation Program with Integrated Circuit Emphasis), a tool for electronic-circuit simulation and modeling.
An ac6 file stores the results of an AC analysis in the frequency domain. It belongs to the simulator's output rather than being a circuit-design or simulation-input file.
The file is intended for use with the Windows version of SPICE that generated it. It is a specialised simulation-output format and may not be supported by unrelated circuit-design programs.
Open an ac6 file with the Windows version of SPICE associated with the simulation. The file is normally viewed as part of the simulator's AC-analysis results rather than opened as a standalone document.
If the original SPICE installation is unavailable, a compatible application may be required because general-purpose software does not normally recognise this specialised output format.
The ac6 file extension represents simulation results, so it is not normally converted into another SPICE input format.
To obtain data in another format, open the results in the generating SPICE software and use any export or report function it provides. If that is not available, the simulation may need to be rerun and its results exported in a supported format.

ArtCut, also known as Wentai ArtCut, is sign-design software for Microsoft Windows. It is used to create vector artwork for sign-making and cutting.
A typical .ac6 file contains a vector graphic design saved in version 6 of ArtCut. It is a native project format rather than a general-purpose vector format.
AC6 files are generally associated with older ArtCut installations. Compatibility with other graphics applications and newer software may be limited, so the original Windows program is the most reliable way to use them.
Open the .ac6 file with ArtCut on Microsoft Windows. Use the program's Open command and select the file.
The original Wentai ArtCut program appears to be the only reliable way to read these files. If ArtCut is unavailable, obtaining a copy of the original Windows software may be necessary to access the design.
Open the .ac6 file in ArtCut and use the program's export or Save As function if the required output format is available in that installation. The available export options can vary between ArtCut versions.
ArtCut likely had some form of export function, but this cannot be reliably verified. If ArtCut cannot open the file, conversion may not be possible without access to the original software.
