  Unlike using bitstream file *.bit like LatticeSC or LatticeECP3 family, LatticeXP and LatticeXP2 have JEDEC file output format for programming. When using ispVM to program device through JTAG interface, there is no extra step. But to program a EPROM, ...

• JEDEC File USERCODE location: When editing USERCODE of the JED file at Program File Utility editor, the USERCODE data was updated on U field but not on the config data. When editing USERCODE of the JED file at Diamond Spreadsheet View, the USERCODE data was updated on both U field and config data.

  There are two different USERCODE for two different memory blocks. One for SRAM and one for FLASH. The SRAM USERCODE stored in the bitstream USERCODE frame and the FLASH USERCODE stored in the U field of the JEDEC file. Using the Diamond Spreadsheet ...

• 2504 - Can I use same JEDEC file or bit file to program different speed rating parts?

  Solution: Speed rating will define some characteristics of the parts, like how fast the part can run, and if it is commercial or industrial part. So if you want to use same JEDEC or bit file to program different speed rating part, your timing ...
