3.1.1. Avalon® -ST Configuration Scheme Hardware Components and File Types
You can use the following components to implement the Avalon® -ST configuration scheme:
- A CPLD with PFL II IP and common flash interface (CFI) flash or Quad SPI flash memory
- A custom host, typically a microprocessor, with any external memory
- The Intel® FPGA Download Cable II to connect the Intel® Quartus® Prime Programmer to the PCB.
The following block diagram illustrates the components and design flow using the Avalon® -ST configuration scheme.
|Programming File Type||Extension||Description|
|Programmer Object File||.pof||
The .pof is a proprietary Intel® FPGA file type. Use the PFL II IP core via a JTAG header to write the .pof to an external CFI flash or serial flash device.
|Raw Binary File||.rbf||
You can also use the .rbf with the Avalon® -ST configuration scheme and an external host such as a CPU or microcontroller.
You can program the configuration bitstreams or data in the .rbf file directly into flash via a third-party programmer. Then, you can use an external host to configure the device with the Avalon® -ST configuration scheme.
If you choose a third-party microprocessor for Avalon® -ST configuration, refer to the Avalon® Streaming Interfaces in the Avalon® Interface Specifications for protocol details.
