first off I am new to this software and only begun replicating a circuit two hours prior to posting so a lot of information and skills are not known to me. I am trying to make a working replicate of a board and it requires operational amplifiers, i have been able to section the board into pieces and have gotten the part without the OpAmp to simulate, however once the OpAmp is added in the simulation fails to run (with no error log) and the border around the button turns red. Browsing the forms i have made sure that my OpAmp has a spice model and that has not resolved my problem. i am very new to this and help would be greatly appreciated.
