Reconfigure FPGA another using NIOS II SoC

There are plenty of ways to dynamically reconfigured FPGAs. However, the development kits you have listed probably do not support reconfiguration by another board, simply because that is not something needed on a development board.

The four FPGAs on this board are dynamically reprogrammed by the PowerPC and FPGA seen on the right-side of the image:

This document describes reconfiguration:

A NIOS II processor could be used to enable a reconfiguration controller like this, or it could "bit-bang" the passive serial interface on the FPGA.

Thank you dave. This actually helps. Cyclone IV devices are not supported for this which are the FPGAs included on above kits. But anyway these links lead to some valuable information.

Thanks

The Cyclone IV devices support passive serial mode and configuration from SPI flash. Take a look at the TS4 design documentation on this page:

https://www.ovro.caltech.edu/~dwh/wbsddc/

(The board never made it to the 'real-world', but the design files have useful info)

If you need fast configuration, then you can use a MAX II or MAX V device as the programmer (passive serial controller), and Quad-SPI flash as the data source. The MAX II/V can read the flash at up to 100MHz, so you can program the Cyclone IV fairly quickly.

Cheers,

Dave
