I am using the command "export_simulation -simulator vcs_mx" in Vivado 2016.2, however it fails with the following error:
To work around this issue in Vivado 2016.2, use vcs with -simulator in export_simulation instead of vcs_mx.
export_simulation -simulator vcs
Both "vcs_mx" and "vcs" should be supported for use with export_simulation. This issue will be fixed in a future release of Vivado.
