Modelsim error: Failed to open file "mem_init.mif" for reading?

[Altera_Forum]

Hey guys: 

 I instantiated a synchronous RAM megafunction in my project and successfully compiled in Quartus and Modelsim. But when I run the simulation there is no waveform. I checked the Modelsim transcript it shows an error and two warnings: # ** Warning: (vsim-3534) [FOFIR] - Failed to open file "mem_init.mif" for reading.# No such file or directory. (errno = ENOENT) : /opt/altera/13.0sp1/quartus/eda/sim_lib/altera_mf.v(187)# Time: 0 ps Iteration: 0 Instance: /proc_testbench/DUV_2/altsyncram_component# ERROR: cannot read mem_init.mif.# ** Warning: (vsim-7) Failed to open readmem file "mem_init.ver" in read mode.# No such file or directory. (errno = ENOENT) : /opt/altera/13.0sp1/quartus/eda/sim_lib/altera_mf.v(45501)  It seems that Modelsim cannot find the initial memory file. How can I solve the problem? Thanks in advance!  Yumeng

the mif file needs to be in the same directory that the simulation is run from.

Thank you so much! It works!
