Hi there, 

i built a project with a part which is created with the sopc builder. 

the sopc block contains a nios processor which has the name cpu_0. 

when i compile my project and have a look at time quest i saw that there is a problem. 

the quartus includes 2 entities which are called cpu_0_test_bench.vhd and cpu_0_oci_test_bench.vhd.  

what are these files doing and why do quartus include testbench-files? 

does anybody know an answer? that would be very nice! 

cheers spitzinger
