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.
