    Hi,

    I infer that using multiple parameter sweeps is similar to nested "for-next" loops. (If that is not correct then ignore the remainder of this question and please correct my misunderstanding.)

    I was attempting to work through the example on p28 (transistor collector current versus base current and Vce) in http://qucs.sourceforge.net/docs/getstarted.pdf independently without referring to the equation block and parameter sweep variables.

    That didn't work out so I wanted to examine Figure 32 to see where I went wrong. Unhappily, most of the equation block in that figure is missing :(

    Is there any way that I can see the entire equation block for Figure 32 ?

    Thanks,
    Randy

    PS: I did look through the archives but didn't find a solution, found a number of questions that were similar to mine ...

     
    • Is there a simple way to convert the design file to i.e DXF format ?.

      For microstrip layout the electrical performance is defined by the physical
      design, thus transferring the design to PCB layout is of vital importance.

    Randy, You are right, multiple optimizer blocks can be nested like a for loops. For Opt2, you chose Opt1 as the simulator.

    Morten, there is no way to convert a qucs schematic to dxf yet the way you want it. But before we differentiate from the subject, please create a new topic if you have a totally unrelated question. The topic here is the optimizer, not dxf or pcb layout.

    Thanks, that is a great tool - I'll continue experimenting until I master it :)

    This is excellent !

    I was making the problem WAY too difficult - I had structured four or five equations in the equation block, attempting to replicate the curve tracer example in the "getting started" manual.

    All that was required was one simple expression - just like the example, LOL. Thanks very much for all of the fine work that went into this application !
