Description

When importing functions/tasks in System Verilog Interfaces, ports get connected incorrectly.

Does Vivado Synthesis support import methods (SystemVerilog functions and tasks) from the System Verilog interface?

Solution

Starting with 2012.4, Vivado Synthesis does support import methods (SystemVerilog functions and tasks) from the System Verilog interface.

Following is an example of an import method that works:

// function define within an Interface

function example_test (.....);

// Import method

modport test (input a, b, import function example_test( ));
