triple speed ethernet on cyclone V E development board

Hi,

Reg_busy is status output signal from TSE IP. You should just monitor it instead of controlling it. But your understanding is correct that it should de-assert low when TSE IP is ready to accept user command.

You can refer to either of below reference design to ensure you connect and initialize TSE IP correctly. These are not NIOS II design that should suit your need.

• Generate TSE simulation example design from TSE IP directly. Then you can run modelsim simulation to learn more about the expected TSE IP signal behaviour
• Or you can also refer to below TSE hardware reference design as guideline

Thanks.
