[avr-gcc-list] The ADC interrurpt can't triger in studio?

[whiteman]

HI,all！

        I used studio4.08 simulate the program as follows:

SIGNAL(SIG_ADC)      //ADC server
{
        ADC_L = ADCL;
        ADC_H = ADCH;
}

int main(void)
{
        DDRC = (1<<DDC5)|(1<<DDC6);
        DDRD = 0xc0;
        DDRB = 1 << DDB0;
        ADMUX = 0x40;                                           //ADC channel 0
        ADCSRA = 0x85;                                          //ADC clock is 
125k
        ADCSRA = (1 << ADIF) |(1 << ADIE) | ADCSRA;
        sei();                                                          
//enable the global interrupt
        Delay(10000);
        ;
        ;
        while(1)
        {
                PORTC = PORTC^0x20;
                Delay(60000);
                ADCSRA = (1 << ADSC) |ADCSRA;   //START ADC
                ;
                ;
                for(;;){}
        }
        return(0);
}

 I simulate this program. I have started the ADC converter and man-made 
modified the interrupt flag "ADIF" to 1,but the studio can't triger the ADC 
interrup, don't execute the server. Whether it is a buy in studion or in gcc??
thanks!!!

best regard
