About Xilinx Parameterized Macros

This section describes Xilinx Parameterized Macros that can be used with Versal architecture Prime series. The macros are organized alphabetically.

The following information is provided for each macro, where applicable:

  • Name, description, macro group, macro subgroup, and family
  • Schematic symbol
  • Introduction
  • Logic diagram (if any)
  • Port descriptions
  • Design Entry Method
  • Available attributes
  • Example instantiation templates
  • Links to additional information

Enabling Xilinx Parameterized Macros

The following instructions describe how to prepare Vivado to use the XPM libraries.
  1. Ensure Vivado can identify the XPMs.
    • When using the IDE and/or the project flow, the tools will parse the files added to the project and setup Vivado to recognize the XPMs.
    • When using the non-project flow, you must issue the auto_detect_xpm command.
  2. Select the XPM template that you wish to use from below.
  3. Copy the contents of the template and paste into your own source file.
  4. Set parameters/generics, and wire ports according to the documentation provided as code comments.
Note: Be sure to read and comply with all code comments to properly use the XPMs.

Testbench

A testbench for XPM CDC macros is available in the XPM CDC Testbench File .

A testbench for XPM FIFO macros is available in the XPM FIFO Testbench File .

Instantiation Templates

Instantiation templates for Xilinx Parameterized Macros are also available in Vivado, as well as in a downloadable ZIP file. Because PDF includes headers and footers if you copy text that spans pages, you should copy templates from Vivado or the downloaded ZIP file whenever possible.

Instantiation templates can be found on the Web in the Instantiation Templates for Xilinx Parameterizable Macros file.
