Qsys tutorial simulation errors

[Altera_Forum]

I am following instructions from the simulation chapter of the Qsys System Design tutorial, but running into compiling errors when I load and execute load_sim.tcl.  

 When it runs to   vlog -sv ./test_program.sv -L pattern_generator_tb_csr_master  it reports error:  -- Compiling module test_program# ** Error: (vlog-19) Failed to access library 'pattern_generator_tb_csr_master' at "pattern_generator_tb_csr_master".# # No such file or directory.

Thanks!
