Vivado System Generator - Black Box GUI still says "ISE Simulator" as a Simulation mode option when configured for Vivado
When using the Black Box GUI in System Generator configured for Vivado, it still refers to the "ISE Simulator" as a Simulation mode option when it should refer to Vivado Simulator.
This is a known issue and is fixed in Vivado System Generator 2013.1 and newer releases.
