2012.4 - Simulation with Vivado HLS leads to error

描述

When running Vivado HLS simulation of a design, the following error occurs:

@I [LIC-101] Checked in feature [HLS]

解决方案

The issue is caused by the improper use of #defines, for example:

#ifndef __SYNTHESIS__
#define __SYNTHESIS__
#endif

As a result of this, there is time keeping code being kept from the benchmark that is required for the co-simulation.

This is causing the failure.

 

Additionally, -I for files not included in the design needs to be removed from the flags along with the -std=99 options.
