PSpice will change your circuit file so that if you\double-click on it you will run the simulation again\if (and only if) all of these conditions these are met:\ 1) You have enabled this feature;\ 2) You allow the simulation of the circuit file to finish;\ 3) There are no errors during the simulation;\\You will find this useful for running lengthy simulations\overnight, since you may shift-click up to 8 files.\\You may still Edit the files, if, for example, you need\to change a component value, by double-clicking on your\favorite Editor, then opening your circuit file.\\Click on ENABLE to enable this feature;\Click on DISABLE to disable this feature.\
