Board-Specific Design Issues
The development board is optimized for Networking applications. As such, Achronix has
configured the SerDes and the IOs at specific pins on the HD1000 device. You must maintain
these in any changes that you make to the device as you work on your system development.
Achronix has made this easy for you through a template for ACE that you can use as a tool to
avoid inadvertent changes to the configuration.
You must also maintain the clocking structure implemented on the board for any changes
that you make while using the board as a development platform. For your new designs, you
may use the flexibility provided by the HD1000 to implement your own clocking schemes.
