The default starting time is zero, so we didn't need a second entry in the example circuit. The second line shows Maximum Time Step . MicroCap simulates operation of a circuit by stepping in time. At each step, the program calculates parameters and compares them with the previous calculated values. If a circuit contains capacitance or inductance, the program also monitors the time rate of change of the charge and flux.
Internal algorithms control the size of the derivative.
If it is too large, the time step is decreased. If the maximum time increment is too large, the resolution suffers, while if it is too small, the program takes a long time to run. You can often smooth a resulting curve by reducing the maximum time step. Note that we have set this to 5 nanoseconds. This means that there will be at least 200 points within the 1 microsecond analysis window.
