Jam File (.jam) Definition

An ASCII text file (with the extension .jam), in the STAPL format, that stores programming data for programming, configuring, verifying, and blank-checking one or more devices in a JTAG chain. You can use Jam Files with the Quartus® Prime Standard Edition Programmer or in embedded processor-type programming environments. You can program all Altera devices supported by the Quartus® Prime Standard Edition 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 by pointing to Create/Update,and then clicking Create Jam, JBC, SVF, or ISC File on the File menu.

Important: Programmer ignores all programming options you choose when you create multiple device (.jam) or (.jic) files. You can use generated (.jam) files with the Jam STAPL Player to apply programming options. However, for a multi-device (.jam) file, the programming options you choose apply to all devices in the JTAG chain that have a data file.

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