Example of a configuration chain to program core logic of a FPGA
.. option:: num_regions="<int>"
Specify the number of configuration chains to be used across the fabrics. By default, it will be only 1 configuration chain. The more configuration chain to be used, the fast configuration runtime will be, but at the cost of more I/Os in the FPGA fabrics.
Frame-based Example
~~~~~~~~~~~~~~~~~~~
The following XML code describes frame-based memory banks to configure the core logic of FPGA.
