Matlab hdl coder examples1/19/2024 After you generate the custom IP core, the IP core files are in the ipcore folder in your current directory. In the Simulink Toolstrip, in the HDL Code tab, click Generate IP Core. Use the Clock Settings tab to configure clock-related settings for the IP core.Īfter you configure the IP core settings and mappings for your design, you can generate an IP core. Use the General tab to configure top-level IP core settings such as the name of the IP core and whether to generate an IP core report. In this example, the input port x_in is mapped to an AXI4-Stream Slave interface and input ports h_in1, h_in2, h_in3, and h_in4 are mapped to the AXI4-Lite interface, so HDL Coder generates AXI interface accessible registers for them. In the Configuration Parameters dialog box, set Reference Design to Default system with AXI4-Stream interface.Ĭlick Apply to save your updated settings.Ĭonfigure your design to map to the target hardware by mapping the DUT ports to IP core target hardware and setting DUT-level IP core options. If Project Folder is empty, HDL Coder saves the generated files in the current directory. Optionally, you can use the Project Folder parameter to specify a top-level folder for any generated folders and files. In the Configuration Parameters dialog box, set the Target Platform to ZedBoard and Synthesis Tool to Xilinx Vivado. In the HDL Code Generation > Target tab, set the Workflow parameter to IP Core Generation. Alternatively, in the HDL Code tab, click Settings to open the Configuration Parameters dialog box. In the HDL Code tab, in the Output section, set the drop-down button to IP Core. To operate in this mode in the HDL Coder Workflow Advisor Task 1.2.Set Target Legacy Frame-Based Modelingĭesign your algorithm to operate on a stream of samples and model the data signal asĪ vector. Model Design for Frame-Based IP Core Generation. To map frame ports ( vectors, matrices, and complex matrices) to anĪXI4-Stream interface use the frame-to-sample optimization. You can design your DUT to operate on frames of data and map the data ports to a You can find the addressįor the programmable TLAST register in the IP core generation report. Reset to zero and the TLAST signal is asserted early. Length register is changed in the middle of a frame, the TLAST counter state is You can change the default frame length during run time. When the IP core has an AXI4 Slave interface, theĭefault frame length value is stored in a programmable register in the IP core. The default frame length value can be setīy using the AXI4-Stream interface options in the Target Interface Table. On the AXI4-Stream Master interface, theĪutogenerated TLAST signal is asserted when the number of valid samples counts Slave interface, the incoming TLAST signal is Which is used to indicate the end of a frame of data. The AXI4-Stream interface on your DUT can optionally model a TLAST signal, Disable delay balancing for the Ready signal If you enable delay balancing, the coder inserts one or more delays on Want to generate an AXI4-Stream interface in your IP core, in your DUT interface, Use the simplified AXI4-Stream protocol for write and read transactions. Handshaking mechanism between valid and ready signals, and supports bursts of The simplified protocol requires fewer protocol signals, eases the Logic that translates between the simplified protocol and the actual AXI4-Stream When you run the IPĬore Generation workflow, the generated HDL code contains wrapper Protocol and instead can use the simplified protocol. You do not have to model the actual AXI4-Stream To map the design under test (DUT) ports to AXI4-Stream interfaces, use the You can specify how HDL Coder packs the data by using the Packing Mode. HDL Coder packs the vector elements together and treats the vector as a single If you model the data signal as a vector, in the HDL Coder Workflow Advisor Task 1.2. You can model the data signal as either a scalar or a When you want to simulate the data signal as a stream of samples on the DUT boundary, Ready signals, use the sample-based modeling style.
