Editing Programmable logic device (section)

== PLD programming devices ==
A [[device programmer]] is used to transfer the Boolean logic pattern into the programmable device. In the early days of programmable logic, every PLD manufacturer also produced a specialized device programmer for its family of logic devices. Later, universal device programmers came onto the market that supported several logic device families from different manufacturers. Today's device programmers usually can program common PLDs (mostly PAL/GAL equivalents) from all existing manufacturers. Common file formats used to store the Boolean logic pattern (fuses) are JEDEC, Altera POF (programmable object file), or Xilinx BITstream.<ref>[http://www.pldtool.com/pld-file-formats PLD File Formats]</ref>
