Vivado - IP core instantiated in VHDL

martingaraj

Is there a way to use IP cores directly in code (VHDL/Verilog) instead of placing them into Block Design (graphical user interface) ?

 

May I ask for an example with Floating Point Operator (in VHDL/Verilog) ? How to initialize it (settings of the core) ? (because the IP core can be set to provide different operations)

 

 

The reason:

- compact code (without the need to switch between code and graphical user interface / Block Design)

- less work

- Block Design is utilized just for top view

    Yes, there is, at least in Vivado 2017.2:

    - Open the IP catalog from Flow Navigator

    - Choose the IP you want to include in your VHDL/ Verilog and double click

    - In the pop up asking whether to add it to a block design, or customize it and add it as RTL, select this last option

    - Customize the module and click OK, this should also generate the products and the IP should apper in the Design Sources hierarchy

    - In Design Sources, highlight the IP and in Source File Properties, copy the path where it is

    - Open that folder and open the file ending with vho, there you will find enclosed in comments, both the declaration and instantiation templates, copy them and paste in your file. Remember to replace the signals to what the instance is connected to (not the ones in the declaration)
