My design works correctly in Vivado Design Suite 2014.2.
After I upgrade it to Vivado 2014.3/2014.4, I receive numerous errors like the following in Simulink Simulation:
Sometime there is only one internal error related to a constant.
When I re-run it, it repeatedly generates the above error again.
The issue only occurs when the design reaches a certain level of complexity.
A smaller design works fine.
What can cause this problem?
This is a known issue related to how Sysgen works with DocBlock in 2014.3 and 2014.4.
It will be fixed in a future release of Vivado Sysgen.
For Vivado 2014.3/2014.4, follow the instructions below to install attached patch:
