| very slow simulation |

dear all
i am using the following code in order to rotate a motor forward and backward related to the value of the potentiometer which connected to the ADC channel 0 and Channel 1
when i run the simulation on the proteus the simulation is very very very slow and i can't change the state of the pot. meter , it is not from my version all projects run perfectly but this not.
this is my code,, the second problem which i did not found any solution for it is that when i run the simulation there is a flashing high on pin c4-c7 i dont know why .plese help
please help me to find what i have to do
