An ASCII text file (with the extension .jam), in the Jam^™ device programming and test language, STAPL format, that stores programming data for programming, configuring, verifying, and blank-checking one or more devices in a JTAG chain. Jam Files can be used with the Quartus^® II Programmer or in embedded processor-type programming environments. You can program all Altera^® devices supported by the Quartus II software, and EPC2, EPC4, EPC8, and EPC16 configuration devices, with Jam Files. The JTAG chain can contain any combination of Altera and non-Altera devices that comply with the IEEE 1149.1 JTAG specification.

You can create Jam Files with the Create/Update > Create Jam, SVF, or ISC File command (File menu).

You can also create Jam Files using the Files tab of the Configuration Device Options dialog box, or using the Programming Files tab of the Device & Pin Options dialog box..
