In using a circuit simulator such as PSIM, how does one choose an optimal time constant T for the integrator/differentiator?

Use of an integrator/differentiator block requires selection of a time constant for the block. How can one go about selecting the optimal time constant T? E.g. a 5kHz, 2Vpp, duty 0.5 triangular...
