    Locate a component by its reference on PCB - possible ? Reply

    Hello,

    Locate a component on PCB (with zoom on it) by its refernce on is very useful function, especially on complex PCBs with thousands nets/components. But it seems that this feature is missed in OrCAD Allegro (or it's hiden by some sophisticated interface).

    When I specify the component reference in the Find by Name entry (please, see the picture in attachment), nothing happens !

    Moreover, when I move cursor out, the entered text disappears !!!

    Is it bug, or I missed something ?

    Thanks in advance.

    Pavel.

    Pavel,

        Due to lack of power I cannot verify this exactly but...One thing you can do is toggle your shadow mode.  I cannot recall whether you have to disable custom colors or not??  Then when you use the find feature it will highlight the part.  I agre,e to have it zoom in on the part would be nice.

    Using 16.5 revision.

    When I select find, symbols, find by name, r111 (example).

    It zooms into the area and highlights the symbol and reference desiginator.

    Hello Ken, Carvey,

    I tried your suggestions. Unfortunately don't work. When I specify the reference of component (J60 as an example, please,see the picture) and then click OK, nothing happens - the component isn't highlighted/zoomed. And this for 2 filter options - Component/Symbols.

    Regards.

    Pavel.

    Works !!!

    I erroneously used Design Object Find Filter instead of Find by Name feature. This last works fine with 2 options - Comp (or Pin) and Symbol (or Pin). Proceeding in this way the tool finds specified component by its reference and zoom on it.

    Regards.

    Pavel.

    Incredible !!!

    Again doesn't work !!! The tool does select the component (counter "Number of selected objects" on the bottom bar increases) but doesn't zoom on it !!! There is probably some misterious option(s) somewhere that is responsible for ZOOM.

    Where this "misterious" option can be found ???

    Regards.

    Pavel.

    I don’t know of any special setting for this.

    When I select the FIND icon and select SYMBOL and select a reference designator the program zooms into the selected component and also highlights it as well.

    I suggest you contact Cadence support or your reseller for help.

    Hello Carvey,

     Thanks for feedback. First where did you find FIND icon ?

    I searched everywhere - menu, toolbars, etc. ... in my version of Allegro 16.5 there is no such control. But after doing some manipulation the method proposed in one of my previous mails (considered as solution) became functional again ... I don't understand what happened ... I have impression, that the tool needs some user activity in order to "activate" certain options ?

    In anyway it seems I've found method that works immediately after Allegro is launched:

    1. Clear filter "Number of selected objects" in the right-down corner
    2. Type component reference in the "Find by Name" edit field, following by Enter
    3. Click on "Zoom on selection" tool (on the toolbar) --> selected component becomes zoomed

    The drawback - each time one should clear the filter "Number of selected objects"

    Regards.

    Pavel.

    I don't have 16.5 so I'm not sure, but have you tried going into "Show element" first then trying using the find by name?

    Pavel,

    As initially suggested by oldmouldy, check out the rather long thread-discussion-analysis on this forum regarding the "Find/Zoom" operation.  No need to repeat.

    Indeed it also works. After clicking on "Show element" zoom option became activated. Then when I type component reference in the "Find by Name" (followed by Enter), the component is zoomed and "Show Element" window opens (window where are displayed different parameters of the component -  Reference, Package, Device Type, Value, etc.). But once activated, "Show element" remains active: recurring clicks on "Show element" have no effects. But, of course it's minor drawback.

    Regards.

    Pavel.

    A very handy Macro from a prior discussion assigned to the f key. Add this to your env file to find symbols by reference dez.

    Works Great !

    funckey f "prepopup ; pop dyn_option_select 'Selection set@:@Clear all selections' ;set prompt ; prompt 'Find Ref Des' ; refdes $prompt ; zoom selection"

    You can also modify it to find nets, in this case it uses the n key.

    funckey n "prepopup ; pop dyn_option_select 'Selection set@:@Clear all selections' ;set prompt ; prompt 'Find Net Name' ; net $prompt ; zoom selection"

    Thanks Scott
