    Passing measured voltage as a .model parameter Reply

    Does anyone know if it's possible to pass a sensed voltage at a given node in a circuit (e.g. V(1,0)) as a parameter in a .model statement? I would like to use a control voltage to a part to vary the DLYTY parameter value in a udly model type. I am attempting to create a programmable delay part for which the delay provided by the part is directly proportional to the voltage supplied on the delay_control line; for example 20uV supplied on the delay_control line will result in a 20usec propogation delay by the part.

    Any help/advice anyone can offer would be greatly appreciated.

    No, it's not possible to pass a voltage value from a circuit as model parameter to .model. To achieve your objective you need to create a circuit or behavioral expression, which introduces the delay based on voltage. This could be tricky and would depend upon nature of your signal which you want to delay.
