MIG 7 Series v1.3 - Does not support -2L speed grade

Description

MIG 7 Series v1.3 supports Kintex-7 Low Power and Virtex-7 Low Power devices, but it does not support the -2L speed grade in Artix-7, Kintex-7 and Virtex-7 devices.

Solution

To target -2l speed grade devices, youcan generate the design targeting a -2 speed grade in MIG, and, then change the speed grade to -2L in all the implementation files or in your ISE Design Suite project. The required files to modify are listed below:

  • Script file ise_flow.bat/.sh
  • CORE GeneratorChipScope XCO files
    • icon5_cg.xco, ila384_8_cg.xco, vio_async_in256_cg.xco and vio_sync_out72_cg.xco for DDR3 SDRAM
    • icon3_cg.xco, ila256_8_cg.xco and vio_async_in256_sync_out72_cg.xco
  • xst_options.txt
  • set_ise_prop.tcl

-2L support is scheduled for the MIG v1.4 ISE 13.4 release.
