6. Software Selectable Options
The operation of the CrossLink Configuration Logic is managed by options selected in the Diamond design software.
Other FPGAs provide dedicated I/O pins to select the configuration mode. CrossLink uses the non-volatile Feature Row
to select how it will configure. The Feature Row’s default state needs to be modified in almost every design. Use the
Diamond Spreadsheet View to make the changes to the operation of the CrossLink Feature Row which alters the
operation of the Configuration Logic.
The Configuration Logic preferences are accessed using Spreadsheet View. Click the Global Preferences tab and look for
the sysCONFIG tree.
Figure 6.1 shows the sysCONFIG section. The sysCONFIG preferences are divided into three
categories:

Configuration mode and port related

Bitstream generation related

Security related
