VNL OpenGL display question
« on: October 1, 2019, 18:45 »
I am running VNL on a Linux machine I get the following error

Could not initialize OpenGL for RasterGLSurface, reverting to RasterSurface.
Could not initialize OpenGL
Aborted (core dumped)

Does VNL requires hardware acceleration from a GPU and NVIDIA driver installed?  Or is it that it only required OpenGL?
Any suggestions to fix the above error.

Yes, VNL does take advantage of hardware acceleration. You should first try to update your graphics card driver. Note that support for the 2017.12 and 2016.4 versions have already been terminated. Please consider upgrading to 2019.03-SP1, you may apply for a free trial license at https://www.synopsys.com/silicon/quantumatk.html.
