JEDEC is a ASCII text files containing programming information that can be used to configure a FPGA device. JEDEC is generated from ispLever or Diamond when a logic circuit is synthesized. It can be downloaded in the Lattice device through the JTAG port . To do this two things are necessary:
- Programming Cable.
- ispVM System software.
Programming Cable
After completion of the logic design and creation of a programming file with the ispLever software, is necessary a programming cable for programming the devices directly on the PC board. There are a lot of compatible Lattice programming cable.For example this is a very simple and low cost programming cable.
ispVM System
The ispVM software is default installed together ispLever or Diamond software. The default directory is (installation directory Lattice)/Accessories/ispVM System
- The programming cable must be connected to the FPG-EYE JTAG board connector and PC port (can be Usb, serial or parallel).
- Turn on the power of the FPG-EYE board, and launch ispVM software.
- Push Scan button, the software should find the Fpga model. If it don't be sure then the JTAG cable is connected and/or the FPG-EYE is powered.
- Aftre click on FileName/IR-Lenght field will show the Chair Configuration window. With Browes button select jed file in local repository.
- Click on OK button and return on The ispVM main page. Click on GO and start the programming configuration in the FPGA. At end the board is ready for use.
