Electronics Workbench 4 opamp sim bug.
A friend gave me his old EB4 a few months ago because he never used it, and I finally got around to playing with it the past weekend. (Full-blown SPICE etc is too hard for me!) Anyway, I had a nice little opamp circuit chugging along driving a source follower, and the zero voltage point of the opamp supply rails were referenced to the source follower output. This method is interesting because the demands on the opamp are very low as regards slew rate etc. Anyway, I found out that this simulator measures the slew rate of the opamp with respect to earth, not with respect to it's supply rails which in this case are going up and down almost the same amount as the opamp's output.
Do other simulators have this problem?
