Quartus Version 13.0.1 Service Pack 1 together with Qsys 13.0sp1
Modelsim Altera 10.1d (only necessary for simulation of modules)
Instead of Altera Quartus, Xilinx Vivado can be used. (Only tested with Version 2016.1)
Start Quartus and create a new project.
Choose your appropriate device.
Under Device → Device and Pin Options… → Unused Pins choose As input tri-stated with weak pull-up. Without this setting the system will not work later!
Start Qsys and choose Tools → Options. Press Add and choose the fLink repository root path. After pressing Finish flink should be listed in the library section.
Add all your desired subdevices to your system by double clicking on the appropriate entry. Set all the necessary parameters, among them unique_id. Also add an interface module such as a PCI or SPI interface.
Add a info subdevice if necessary. An info subdevice can be very useful for reading the total memory size of the whole device as well as reading the description field. This can be used to cross check whether the right design is loaded in the FPGA.
Connect all the clock sinks as well as the reset sinks.
Connect the avalon master interface of the interface module with the avalon slave interfaces of all the other subdevices.
In the export column double click on the conduit part of every subdevice.
Choose System→Assign Base Addresses. Make sure that there are no empty spaces between subsequent subdevices.
Select the tab Generation Writer on the top and choose VHDL in the Synthesis part. Save the system and click the Generate button.
Close Qsys and change to the Files tab in the project view in Quartus. Add the .qip file from the synthesis folder of the Qsys system.
Set the .qip file as Top-Level-Entity.
Select Analyse and Synthesis.
Open Pin Planer and designate all the necessary pins.
Compile the design and download it.
Start Vivado and create a new project.
Choose your appropriate device.
Under Project Settings General tab change Target language to VHDL.
Under Project Settings IP tab change to Repository Manager and add the flinkvhdl root directory with the green cross.
Create a new Block Design.
Add a ZYNQ7 Processor System to the design.
Open the IP Catalog and add all needed subdevices found under User Repository→fLink→Subdevices to the design.
In the Block Design press Run Block Automation at the left top corner
Than press Run Connection Automation right next to it. Select the two axi interfaces.
Create ports for the Subdevices if nesessary.
Open the Address Editor and make sure that all devices have a Range of 4K and that there are no gaps between two devices. If a info device is used make sure it is on the first memory address.
Add pin mapping.
Create Bitstream and download it
Id and Unique_Id
Every subdevice has a parameter unique_id. The user can assign any unique value to it. Please keep a list with these values.
When a flink device is later scanned and all its contained subdevices read out, every subdevice is numbered with numbers starting from 0. This number is the id. A subdevice can now be selected either by its unique_id or its id.
The unique_id is defined as a parameter when configuring the subdevice in the FPGA. On the other side, id is set at runtime when subdevices are scanned. id therefore depends on the arrangement of the subdevices in a device. unique_id can be kept constant in any arrangement.
An userland application should use unique_id when searching for a subdevice. This ensures that the application doesn't have to be recompiled when more subdevices are added to a FPGA design and the memory arrangement changes.
An info subdevice serves for information purposes only. It comprises the fields unique_id, description and dev_size and has no channels. It can be included in any design if desired. dev_size is very handy if the interface to the FPGA doesn't allow for enumeration. In those cases the info subdevice can be queried for this field. The info subdevice does not have to be at the first address.
The field description can be used to assertain that a specific design is present in the FPGA.
