how to calculate the execution time?

[Altera_Forum]

hi, 

I want to calculate the time of my program, so I use "profiling library" option.   I got a file that contains information on the timing of certain functions in my program.   my question is: how can I use a performance counter to measure the execution time of each function in my program? thks for all members

There is no such thing as "normal execution time" for a testbench. 

It depends of course on your simulation system (P3 800 MHz has other Perfomance than a P4 3GHz). Further on the complexity of your design, next point is the average switching frequency for your design, as a simulator needs to calculate every signal switching. Another point is the testbench itself. You could programm fast testbenches or slow testbenches. A testbench using only sequential signalassignments an wait statements will be quite faster than a testbench, that calculates the stimuli and waittimes or reads them from external stimuli files.
