What is a JAM file?

A JAM file is a CAD file created in the Jam Standard Test and Programming Language (STAPL) format, a standard file format used for programming PLDs (Programmable Logic Devices). It includes the data and algorithm needed to program a PLD. JAM files enable vendor-specific programming requirements to be communicated to PLD programmers in a recognized format.

More Information

JAM files are typically generated by a vendor-specific software program, referred to as the "Jam Composer." PLD vendors then distribute JAM files to customers (device programmers), who program and test a PLD using the "Jam Player." The Jam Player reads the JAM file and provides the facilities needed to program the device in a standard JTAG (Joint Test Action Group) chain. This process used to be carried out using separate command-line tools provided by Altera, but it is now encapsulated in Altera's Quartus design software.

NOTE: JAM files are stored in an ASCII text format. They can be compiled into .JBC byte-code files for a binary representation.

A JAM file may also be a board created by the team-collaboration Figma app to organize ideas. It is saved in the proprietary FigJam (FIG) format, storing design elements that make up the whiteboard or diagram, including text, shapes, icons, images, sticky notes, and tables. Figma users save their boards as JAM files to preserve their ideas and then share them with other Figma users or export them to other formats, such as .JPG images or .PDF documents.

Figma is a two-pronged collaborative tool that provides the following workspaces:

  • FigJam - Create and share online whiteboards for meetings, brainstorming sessions, diagrams, and more.
  • Figma design - Mock up designs for websites, apps, digital products, and other types of user experiences.

Most users access Figma online in their web browsers, but they may also use the app's desktop version for Windows and macOS or on their Android or iOS mobile device. When creating a whiteboard in the FigJam workspace, you can add various design elements to organize and diagram your plans, ideas, etc., then save it to your online account or as a JAM file on your computer.

To save a JAM file with Figma in a web browser or desktop app, click the Figma icon in the upper-left corner and select File → Save local copy (the web browser automatically downloads the JAM file). You can also choose to save your design to the version history connected to your online account by selecting Save to version history instead of Save local copy.

How to open a JAM file

You can open a JAM file with Figma in a web browser, the Windows or macOS desktop app, or the mobile app for iPad. For example, you can open a JAM file with the desktop version of Figma by selecting the Home icon in the upper-left corner and then clicking Import in the upper-right corner.

How to convert a JAM file

Figma can convert JAM files to various file types, including the following formats:

  • .JPG - JPEG Image
  • .PNG - Portable Network Graphic
  • .SVG - Scalable Vector Graphic
  • .CSV - Comma-Separated Values File
  • .PDF - Portable Document Format

To convert a JAM file in Figma's FigJam workspace, click the app icon in the upper-left corner, then select File → Export as.
