How can I determine which boundary scan operations are supported for a given device and package, and what the values are?

A BSDL (Boundary Scan Description Language) file is available for every Lattice device with a JTAG port. You can find the available operations for a given device in that device's BSDL file.


This file, standardized by the IEEE1149.1 specification, describes all information necessary to perform boundary scan testing. Included are register lengths, instruction mappings, the device ID code value, and boundary scan register order.


BSDL files for Lattice devices can be acquired from the downloads section of the Lattice website: BSDL Downloads
