First, if it is linear simulation, it is not necessary to have your own time signal, except you want time domain response only.

You can refer to the following examples:

and this forum post  custom time signals in Lumerical INTERCONNECT

you can follow the steps outlined in the provided documentation. For instance, to generate a 16QAM modulation signal and adjust the electrical signals to fit in the [0,2V] MZM driving voltage range, you would start a new INTERCONNECT project and drag and drop the required elements, connecting them as specified in the instructions. Additionally, you can use the two electrical signals to drive the MZM for modulation.
