    How to model a time dependent impulse current source in hspice

    I apologize for any mistake in my sentences, My mean is the time between the previous and the next impulse, Whole the procedure is done in a loop, and there is a counter for each current source. I don't have any information about the starting time of each impulse and it must be found in a...

    How to model a time dependent impulse current source in hspice

    Assume we have a current source which includes several impulses, there is a time between every two consecutive impulses, this time is measured after ending past impulse and before starting the future impulse. This time must be saved and named as "th",,this time is determined by a counter and...

    How to model a time dependent impulse current source in hspice

    I don't know how l can save time between two consecutive impulses, this is the problem because this time must be saved in each step such as a counter, and also a comparison between th and tf must be done. When the negative condition is met, the counter must reset to zero. And the before...

    How to model a time dependent impulse current source in hspice

    I have a circuit which includes two capacitors, current impulse source and a time dependent voltage source. One of the capacitor is parallel to the current source, The problem is how to design this current impulse source in hspice because the start time of the pulses are not fixed and...

    How to model a time dependent impulse current source in hspice

    I want to model an impulse current source in hspice so that the startup time is determined as follows: If dt<0, current source will be on. Where dt=th-tf, th:is the time has been passed from beginning of the simulation , tf=1/v(3), Where v(3) is voltage of the node named 3, This if condition...
