You can use the SVF Player without opening a project. The Efinity SVF Player requires a JTAG cable or mini-module with the FTDI n232H chipset.

You can use the SVF Player to execute any JTAG commands on the following Efinix FPGAs:
  • Trion T20 in F324 and F400 packages
  • Trion T35 in any package
  • Trion T55, T85, and T120 in any package
  • All Titanium and Topaz FPGAs in any package
You can use the the SVF Player to execute any JTAG command except PROGRAM for the following Trion FPGAs:
  • T4, T8, and T13 in any package
  • T20 in W80, Q144, F169, and F256 packages

You can also use the SVF Player to execute JTAG commands for non-Efinix devices in a JTAG chain.
