Honored Contributorwhich header file can i use for this function? --- Quote End --- are you sure? I have it in the file components/altera_avalon_performance_counter/HAL/inc/altera_avalon_performance_counter.h ... it's the last function declared! --- Quote Start --- originally posted by ruling@Feb 7 2006, 11:55 PM 2. when i run the program using nios ii instruction set simulator, it gave me a
warning : "sopc builder system component performance_counter_0 is not
supported by the simulator. simulation may be incorrect if your software
attempts to access it".

--- Quote End --- I think the simulator only implements a few basic peripherals... --- Quote Start --- originally posted by ruling@Feb 7 2006, 11:55 PM 2. also i got an error: "error! failed memory access in
component cpu_0 - reading data 0x0 from uninitialized memory (addr =
0x3ff68) error! : simulation failed in component cpu_0 at instruction 3257
(pc=0x21e4 instr=0x24000317)."

--- Quote End --- In the simulator, You cannot read from a location that has not been previously written... that's typically a bug in the software (unless you want to read some random values...)... In any case look also at this post: http://forum.niosforum.com/forum/index.php?showtopic=314&hl= (http://forum.niosforum.com/forum/index.php?showtopic=314&hl=) --- Quote Start --- originally posted by ruling@Feb 7 2006, 11:55 PM so, which tool except modelsim can i use to
run the program with performance counter? actually, modelsim is very slow if
running a very large code.
