I am using an integrator macro in my circuit. The input to this macro is a battery, and I would expect to see a linear waveform with a slope equivalent to the battery voltage as my output. The output I am receiving is a DC waveform at 100KV. What is happening?
In the Transient Analysis Limits, disable the Operating Point option. This will start the transient analysis with all node voltages and inductor currents at zero instead of starting at the DC operating point calculation. The operating point calculation is skewing the output of the integrator because by definition the integrator needs to know the value of the previous data. When the operating point is disabled, it can use the zero values as its previous data. The operating point should be disabled for transient analysis when the INT or DIF macros are used in a schematic.
