[AVR] how to simulate ATMEGA 328 in protues??

[Deexith Hasan]

#include <avr/io.h>
#include<util/delay.h>
void delay()
{
_delay_ms(500);
}

int main(void)
{
DDRB=0xFF;
while(1)
{
PORTB=0XFF;
delay();
PORTB=0X00;
delay();
}
return 0;
}

a simple blink program compiled in WINAVR and created hex file.....
when i simulate in protues i got 800ms delay at 40MHZ external crystal......

how to set clock fuses for 10Mhz crystal...in WINAVR to create 500ms delay and how to simulate the same

Proteus does not simulate crystal oscillators. Clock specified in properties.
