Simulator other than VCS

In the Eval User guide there is this disclaimer:

Requirements
The example test simulation environment included in this release is designed to work with Syn-
opsys VCS (K-2015.09-SP2). GNU Make is used to build the RTL into a simulator and run the
included binary test files.
I don’t have access to that. Has anyone successfully compiled this core with Questa or ius/xcelium ?
