All about XSA Files

The XSA file type is primarily associated with Vivado.

XSA	File extension: XSA

What is an XSA file

XSA files mostly belong to Vivado. XSA files are used primarily to store Xilinx FPGA hardware design data. They are essentially ZIP archive containers that hold project files such as netlists, configuration scripts, bitstream data, and other design elements used in hardware development.
Main use-case:

FPGA hardware design: These files, managed by tools like Vivado, bundle multiple design files into one archive.
Compressed animation data: A smaller group of XSA files contains compressed animation data for viewing in MOS Datafile Viewer and works with the BioWare Aurora Engine.
MSX disk image: Some XSA files are created as disk images for MSX systems running under XS-DOS, often used with MAME.

To inspect or work with an FPGA design XSA file, it is best to use Vivado. However, if you suspect your file is not a design archive, you might try opening it with a standard ZIP tool by renaming the extension. This method can reveal more about its internal structure.
FilExt.com note: Use the appropriate specialized software to view or modify the file contents depending on its intended purpose.

How do you open XSA files?

You need a suitable software like Vivado to open an XSA file. Without proper software you will receive a Windows message "How do you want to open this file?" or "Windows cannot open this file" or a similar Mac/iPhone/Android alert. If you cannot open your XSA file correctly, try to right-click or long-press the file. Then click "Open with" and choose an application. You can also display a XSA file directly in the browser:. Just drag the file onto this browser window and drop it.

Programs that open and convert XSA files:

Vivado
See the previous paragraphs to learn more about the main application. XSA files are often referred to as Vivado cads because this type of file is primarily created or used by this software.
XSA (Raw Disk Image) by XelaSoft
XSA (XelaSoft Archive) format is a special compression format designed to be able to distribute raw disk images (DSK files) via the Internet. This file format is classified as Archive.

XSA file format:

Each file has a definite file format, that is, how the stored data is arranged in the file. The first characters in a file identify the file format, for example, HTML files start with the bytes <html>. If the file extension or signature does not match the file format, errors will occur when opening or editing the file. So you need a detailed analysis of a file to find out the format and the associated program. In the following you will find our evaluation of the XSA files:

The XSA file extension is not widely used. Such a file is mainly used by one program with a specific format. The following file formats are most commonly found in XSA files:

75% of all XSA files are based on the zip format, so several files are combined and compressed into one XSA file. The 8 to 22 compressed files are called ps7_init_gpl.c, ps7_init_gpl.h, ps7_init.c, ps7_init.h, ps7_init.html, ps7_init.tcl, psu_init_gpl.c, psu_init_gpl.h, psu_init.c, psu_init.h, psu_init.html, psu_init.tcl, sysdef.xml, xsa.json and xsa.xml. If you want to see the included files and images, simply rename the file extension to .zip and double-click it. The average file size is 1 MB with most files being between 160 KB and 5 MB in size. design_1_wrapper.xsa is a typical file name. Such XSA files store data about wrapper, design, system, cloud, preprocess, filter, sobel and gpio.
7% of all XSA files start with the bytes MOS DATAFILE2.0 crucial for this file format. If you open these files in a text editor, you will see only illegible characters. The files are often between 7 KB and 310 KB in size. The keywords MOS DATAFILE2.0, COMPRESSEDANIMATIONSET2, DIRECTORYHEADER, QUATPALE and SEQUENCES are typical for these files.

All other XSA files (18%) have no consistent format, the following 4 formats exist: XelaSoft Archive compressed data and config. Tagged as postprocess, blackboard, colour, render, board, beta, bist or revd. If you want to find out what your XSA file contains, drag and drop it onto this page.

How to solve problems with XSA files

Associate the XSA file extension with the correct application.
Update your software that should actually open archive files. Because only the current version supports the latest XSA file format. Search, therefore, e.g. on the manufacturer website after an available Vivado update.
To make sure that your XSA file is not corrupted or virus-infected, get the file again and scan it with Google's virustotal.com.
