I want to add a delay to my analog output to test some cases. How can I do this? I use the "delay.sym", which gives me an error.

Use

devices/ngspice_analog_delay.sym

. test schematic attached shows how to use this ngspice delay primitive. See paragraph 8.2.33 Analog delay in ngspice manual.

the analog delay ngspice primitive can be configured as a fixed delay or variable delay (controlled by a ctrl input between 0V and 1V)
