simulation error

This error message appeared when i try to simulate this circuit by proteus software (file attached)

what could it be?and what should i do for making it correctly?!

There is no model for the IC labelled DS1. I don't know anything about proteus software so I'll have to leave it for someone else to help you.

I'd say the spice model for the IC is missing, I uploaded the file so you can fix it, download it here

**broken link removed**

copy the file to the folder called "MODELS" in your Proteus 6 install directory

error occured after simulating:

any help please!

especially for: FATAL: [U1] Program or EEPROM data has invalid address [2000] for this device

By the look at what is happening you are either not correctly defining the device (PIC micro) your using, or not defining it at all.

it is: PIC16F628

i KNOW NOTHING, but it appears that the program for the PIC is part of the simulation and it has an error.

can you post your code please

code file attached:

I'm getting the following error when trying to compile the program

Error[113] D:\TEMP.ASM 643 : Symbol not previously defined (TMRIL)

Click to expand...

Could this be the issue?

Just in case he didn't notice?, it should be (TMR1L) and not (TMRIL).

i don't know that's the next step for me!
could you tell me please?!

Did you correct your program as Nigel suggested?

Honestly , i didn't understand what you made exactly and which compiler for what purpose have you used.what about TMRIL?
and also how can i modify my program as i have asm and hex file?

sorry but i'm getting lost.
thanks a lot

Perhaps you should try reading the replies?.

It's NOT TMRIL it's TMR1L - a ONE not an EYE.

The timer is TMR1. If you don't use the number, the system does not understand.

I replaced all TMRIL in that file with TMR1L so could you compile it to hex file cause i don't have the compiler?
can you also try to simulate the circuit and give the results to me?

or at least some comments which will be very appreciated!

regards

I got a compiler called PIC simulator IDE and after I replaced every TMRIL with TMR1L,the following error messages have appeared:

any help?

Looks like your simulator is crap!.

Presumably it comes with instructions or a help file?, try reading them - the errors you show don't look like errors in the code? - why not use MPLAB?, the official MicroChip simulator (assuming you want to use a simulator at all?)
