# ADC Stimulus file with MPLAB SIM (Simulation with MPLAB SIM)

I'm trying to simulate my project using MPLAB SIM but I get the following message:

How do I create an ADC Stimulus file?

Info that might be useful:

• MPLAB 8.30.00.00
• PIC18F4520
• PicKit2 programmer.

• Problem is that I am reading from 2 ADC channel and I need to simulate both. So, injecting to ADRES, how will I link it to a specific ADC channel? – Buhake Sindi May 20 '12 at 21:16
