How To Write Via Jtag - Mitsubishi Electric NZ2GN2S-D41P01 User Manual

How to write via JTAG

In this method, the personal computer and the FPGA module are connected one-to-one with the FPGA download cable, and
the configuration data is written to the FPGA module via JTAG. Use JIC format or SOF format files as configuration data.

software
• Some FPGA design software functions download and use SOF format configuration data. For details, refer
to the FPGA design software manual.
• Writing via JTAG has restrictions on the usage environment. Use it in an environment free from noise, such
as for desktop verification during user circuit development.
