XSVF is an extension that is given to files related to Xilinx devices and software. XSVF files are used to store data related to testing embedded systems in Xilinix devices. It is a compact binary version of the text file. This solution uses the JTAG protocol. These files may be supported by the ISE Design Suite.

This solution is used in the process of testing FPGA programmable circuits (a type of PLD chip that allows it to be programmed multiple times without having to be disassembled from the device).
