JEDEC is a ASCII text files containing programming information that can be used to configure a FPGA device. JEDEC is generated from ispLever 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 software. The default directory is (installation directory Lattice)/Accessories/ispVM System

  • The programming cable must be connected to JTAG FPG-EYE board connector and .
Jtag connector
  • Now power your FPG-EYE, then we can open ispVM software.
Open ispVM software
  • After we have pushed on Scan button, the software should find the Fpga model like in the follow image.
Scan on ispVM software
  • Then we click on FileName/IR-Lenght and then we click on Browes and select jed file.
Select jed file
  • Now we click on OK and we return on ispVM main page then we click on GO and program the FPGA on FPG-EYE board.
