compiling quartus II verilog libs for vcs mx ...

[Altera_Forum]

hi, 

 i was trying to compile verilog libs for arria10 fpga family for simulation with vcs-mx. i read online that the vcs-mx tool supported by quartus ii 64-bit version 15.0.0 build 145 is vcs/vcs-mx 2014.03-sp1 for linux. when i do a $which vcs in my linux terminal, i get the following -  /tools/synopsys/vcs-mx_vI-2014.03-SP1/amd64/bin/vcs  now i use tools -> launch simulation libraries compiler to compile the libraries. when i specify the vcs-mx executable location, i get an error saying - executable cannot be found!!! please refer attached screenshot (screenshot-4.png) The nativelink report also says it cannot locate vcs-mx (no other error message)  when i go to tools -> options, i ensure that i have specified the proper path for vcs-mx there as well (refer screenshot altera_EDA_tools_options.png)  I also tried simulating a design from within quartus by switching over to modelsim-altera (in Assignments -> settings -> EDA tools for sim -> modelsim-altera) however when I run the rtl simulation, i get an error saying the license cannot be located for modelsim-altera!  since this is a new installation of altera, please let me know in case this is a compatibility issue for vcs-mx or if i need to set some paths/env variables? i am running on a rhe 6 machine.  thanks in advance!  z.
