JED File – What is .jed file and how to open it?
JED File Extension
Xilinx JEDEC Programming File – file format by Xilinx
JED (Xilinx JEDEC Programming File) is a file format developed by Xilinx for programming FPGAs and CPLDs. It contains device configuration data in a JEDEC-compliant format, including device pinout, timing constraints, and fuse map.
Definition
A JED file, an acronym for Joint Electron Device Engineering Council Programming File, is a text-based file format specifically used in the field of electronic design automation (EDA). It adheres to the JEDEC (Joint Electron Device Engineering Council) JESD7 specification and serves as a standardized method for programming programmable logic devices (PLDs), such as field-programmable gate arrays (FPGAs) and complex programmable logic devices (CPLDs).
Purpose and Features
JED files contain instructions that define the configuration of a PLD’s internal logic. They specify the contents of the device’s programmable memory cells, enabling the customization of its behavior. JED files facilitate the programming of PLDs using industry-standard programming tools and devices. They provide a universal format that enables compatibility between different PLD manufacturers and programming software.
Additionally, JED files include information about the target PLD, such as its device type, package type, and pinout. This information ensures that the file is compatible with the intended device and prevents programming errors. Overall, JED files play a crucial role in the programming and configuration of PLDs, ensuring their reliable and accurate operation in various electronic systems.
JED File Format and Usage
A JED file (Xilinx JEDEC Programming File) serves as an ASCII-based file format used in the programming of Xilinx field-programmable gate arrays (FPGAs). It contains instructions that specify the programming data to be written into the FPGA’s programmable logic elements. Each line within the JED file represents a specific programming operation, with information such as the target memory address, data value, and programming mode. JED files adhere to the Joint Electron Device Engineering Council (JEDEC) standard for programmable logic devices.
Opening JED Files
Several software applications can open and manipulate JED files. These include:
-
Xilinx ISE Design Suite: The official software suite from Xilinx, ISE Design Suite provides comprehensive tools for FPGA design and programming, including support for JED file editing and manipulation.
-
Vivado Design Suite: Xilinx’s next-generation design suite, Vivado, offers advanced features and capabilities for FPGA development, including JED file handling and editing.
-
Text Editors: Basic text editors, such as Notepad++ or Sublime Text, can open JED files for viewing and editing. However, these editors may not provide specialized features for JED file manipulation.
Xilinx JEDEC Programming File (JED)
The Joint Electron Device Engineering Council (JEDEC) file format, with the file extension .JED, is an industry-standard file format used for programming programmable logic devices (PLDs). It provides a common language for describing the programming data of PLDs, enabling interoperability between different programming tools and devices. The JED file format is widely used in the electronics industry for programming FPGAs, CPLDs, and other types of PLDs.
Specific to Xilinx, a leading manufacturer of FPGAs, the JED file format is known as the Xilinx JEDEC Programming File. This file format is used to program Xilinx FPGAs and other devices. It includes detailed information about the FPGA’s configuration, including the programming data, fuse map, device information, and checksums. The Xilinx JEDEC Programming File format is supported by Xilinx programming tools such as Vivado and ISE Design Suite, allowing engineers to program and configure their FPGA devices efficiently.
