Set the DATA0 to the value of the bit we want #Basically, every config bit we send to the FPGA needs to be clocked in. #The following generates the byte stream from the RBF file. #So we need to convert the bits in the RBF file into bytes to send to the FT232RL, setting the DATA0 pin and then "clocking" it in. # each bit in said byte cooresponds to one pin on the FT232RL. #We set the current state of all 8 Bit-Bang pins of the FT232RL by sending it one byte.

The final step is to click the “Generate” button.įirst, I just want to throw all the code out there for people who would like to copy & paste it in it’s entirety, next I’ll break it down and explain its components.

(The CII has an onboard decompression engine) This reduces the number of bits we need to send.

Click on the Properties button and enable Compression.

(This file should be in the root directory of your FPGA’s project after you synthesis the design)

Add the source SOF file to be converted.

Select the Programming file type as “Raw Binary File (.rbf).

(First, open the Convert Programming File tool from the menu.) The graphic below highlights these steps you will need to take:

We will be converting the SOF file to an RBF, Raw Binary File which appears to be easier to work with. However there are other file types available to use for configuration, so much so that Quartus II has a built in tool to convert between formats. Once you “compile” (synthesis) an FPGA design in the Quartus II software, the tool generates a file which contains all the information required to configure your FPGA.

Trigger the Cyclone II into configuration mode.

Open a connection to the FT232RL hardware, and configure it for Bit Bang mode operation.

We then need to “weave” in the DCLK transitions to create a parallel byte stream which will be sent to the FT232RL.

rbf configuration file into a serial bit stream.

Convert the FPGA Config file from SOF to RBF (Raw Binary File) in Quartus.

Let me give you a quick high-level overview of what we must do in order to configure the Cyclone II using the FT232RL, after which we will dive head first into all the juicy details. The second part describes the hardware modifications and connections required to interface the FT232RL to SparkFun’s Cyclone II Breakout board.

The first part in the series describes how to compile and install the hardware drivers in Ubuntu that we need to use to access the FT232RL functions.

You can use free software 7-zip,, to decompress the file.This is the final post in a series of three to explain how to use the FT232RL USB to UART Bridge to program a Cyclone II FPGA. Select “Release: 16.0”, and "Combined Files".ĭecompress the downloaded file and install Quartus Prime. Quartus Prime includes an implementation of VHDL and Verilog for hardware description, visual editing of logic circuits, and vector waveform simulation.Ĭonnection to campus VPN is not required.ĭownload and install "Quartus Prime Lite Edition" via this link Quartus Prime enables analysis and synthesis of HDL designs, which enables the developer to compile their designs, perform timing analysis, examine RTL diagrams, simulate a design's reaction to different stimuli, and configure the target device with the programmer. Intel Quartus Prime is programmable logic device design software produced by Intel prior to Intel's acquisition of Altera the tool was called Altera Quartus Prime, earlier Altera Quartus II.
