Description

addFPGADataCaptureInterface('AllowedConnectivityTypes',`{'JTAG'}`) adds and defines an FPGA Data Capture interface to an hdlcoder.ReferenceDesign object. This argument enables data capture over a JTAG connection and uses internal BRAM resources to store captured data.

These arguments enable data capture over a processing system (PS) Ethernet or universal serial bus (USB) Ethernet connection and use internal BRAM resources to store captured data. In the HDL Workflow Advisor, HDL Coder™ adds connections specified by the Connection_Types argument to the FPGA Data Capture (HDL Verifier required) parameter in theSet Target Reference Design task.

These arguments enable capturing large data of up to two gigasamples by using the external DDR memory available on the FPGA board over a JTAG connection. When you specify these arguments, in the HDL Workflow Advisor, HDL Coder adds the External memory option to the FPGA Data Capture storage type parameter in the Generate RTL Code and IP Core task.

These arguments enable capturing large data of up to two gigasamples by using the external DDR memory over a PS Ethernet or USB Ethernet connection.

Key Considerations

• This interface is supported only for the Intel® and Xilinx® synthesis tools.
• If you do not define this interface in the plugin_rd reference design definition file, the following syntax is applied by default:
  addFPGADataCaptureInterface('AllowedConnectivityTypes',{'JTAG'})

Input Arguments

expand all

Connection types for data capture, specified as a cell array of character vectors. The supported connection types are:

• JTAG
• PL Ethernet
• PS Ethernet
• USB Ethernet

You can specify any or all of these connections if supported by the target board. In the HDL Workflow Advisor, HDL Coder adds connections specified by this argument to the FPGA Data Capture (HDL Verifier required) parameter in the Set Target Reference Design task.

For PS Ethernet and USB Ethernet connections, when you add the device tree to anhdlcoder.Board or hdlcoder.ReferenceDesign object by using the .dtb extension, follow the structure of the examples inGenerate DTB File (HDL Verifier). When you use the .dts extension, you do not need to author the device tree, as it can be dynamically generated by HDL Coder. For more information about generating a device tree for the HDL Coder generated IP core, see Generate Device Tree for IP Core.

Note

• FPGA data capture over a JTAG connection is available for Intel and Xilinx boards. FPGA data capture over a PL Ethernet, PS Ethernet, or USB Ethernet connection is available for Xilinx boards only.
• To enable the PL Ethernet connection, you must add the Ethernet MAC Hub IP in the plugin_board file by using the addEthernetMACInterface method. Adding the PL Ethernet connection in the plugin_rd file, without adding the Ethernet MAC Hub IP in the plugin_board file, results in an error.
