    HFSS plot impedance versus frequency

    Hi, I obtained s11 and s21 of a connector pin in HFSS. Then I need to know its impedance in function of the frequency, expecting of course almost a short at DC. I tried by obtaining the s11 (real and imaginary parts) in a table and then computing the impedance, but obtained almost 50 ohms at DC...

    Simulate a buffer from input to output with IBIS

    An IBIS input model is supposed to work as a load and an IBIS output model as a driver. So, a topology "IBIS output model to IBIS input model" can be easily built. But, I'm trying to simulate a buffer from its input to its output and have the next doubt. I have the "output of the input"...

    Question "breakout"

    have a doubt, when refering to "breakout", its meaning is the routing from the pins of an IC to a distance over the package limits. Or it's about dimensions change in the width of a line?

    What does circuit optimization refer to?

    Re: Circuit optimization Yes what I'm asking about optimization is related with the goals to get in a design and also how to perform an optimization in a spice simulator. I saw that there are some menus about it in TSpice and am going to read something about it. But still wonder if there are an...
