You should not assume that the simulator mimics real hardware exactly, however in this case it may be failing for a similar reason. If SCL or SDA are low during start then a bus collision is assumed, …

PIC12F683 or PIC16F688 assembly or C blinking LED example with XC8 compiler, MPASM or gputils
XC8 has built-in functions __delay_us() and __delay_ms() for creating long delays.
Here is your code modified to run the 12F683 at 8MHz with GP0 toggling at 1Hz. …
