One View into a Schematic or Two?

Posted March 31st, 2014 · 14 Comments · Survey


I came across an ADS feature the other day, and wondered what you think about it. The feature is explained in the video below. Please take a look then come back to this page to vote in the informal, unscientific poll using the radio buttons immediately below the image. Thanks!

What do you think of the ADS multi-view feature shown in the video?

    Hi Colin,

    I have not yet found an application where the second window view to the same schematic helps me, but I’m not confused either. “Neutral” choice is not available, so I voted “useful”.

    What I misunderstood was your question: I was expecting some question about multiple schematic views per cell (aka polymorphism). That’s a most useful feature in my opinion, and I use it heavily.

    Best regards

    ADS with seperate window display is especially useful and with this one can be able to leverage on seperate displays too.

    Hi Colin,

    Came here from Twitter. Thanks for bringing this to the table. I hope the folks in product development get a chance to read the feedback.

    I voted neutral because I hate this multi-view feature.
    I wish I could turn it off. In 99% of my work with ADS it would be off.
    The big problem is screen clutter when you are working on a large hierarchical design with multiple cells and multiple views/windows open. More often than not during an ADS session a schematic view gets hidden under a layout view, an EM view, another schematic, and under one or two Data Displays (Which BTW don’t suffer from this multiview feature. Wasn’t consistency a key UI virtue? )
    To bring a lost view/window to the surface, the logical place to go is the workspace tree. Especially the Folder View provides structure in my work and makes me find sub-circuit views to surface quickly. That works, but this multi-view feature makes the cluttering even worse. Other hidden windows are now even harder to find. Soon only File>Close All helps, but this forces all your open views to be saved, which is often not what you want.

    Thanks, justatoms. This is just the kind of feedback we’re looking for. Thanks again.

    Thanks for adding neutral as I am firmly in that bucket. But then again I have no coherency issues as a single user to a single workspace.
    BTW, I could not read the blue hyperlink letters on the grey background below your video… I arrived at the poll by the context established in the text indicating “after this intro”.

      Thanks, Jim. I’ll try to fix the foreground/background text color issue. That web page is generated by Camtasia and I haven’t yet figured out how to override the defaults.

    Nice to know of this feature. Jury is still out on its usefulness for me. In my opinion, a more useful feature to have would be the ability to open another workspace schematic without closing out an existing workspace. Sometimes I find I want to copy a part of a schematic from one workspace to a schematic in another workspace easily.

      ADS open access libraries have some great features for sharing libraries to simplify copying and pasting pieces of schematics and layouts from one workspace to another. Navigate from the ADS main window to DesignKits>Manage Libraries and then select [Add Library] button. Then browse to the desired workspace and add its library. Be sure to select the “Read-only” Mode before Adding so that it prevents any changes but allows library cells to be opened and copied. This makes it easy to cut and paste from one window to another between libraries, or to copy multiple cells all at once into the working library.

      The brute force way of going into the other workspace and directly copying library cells from one workspace library to another library still works, but it helps if one uses lower case letters for naming the libarary cells for schematics and layouts so that the extra % character used to designate uppercase isn’t making it difficult to read the names. Navigation to the workspace library is made easy by selecting Library View tab in the main window, then right click on the library name and use the >Explore in File System option to jump to the actual folder location.

      Lastly, there is always the user templates if you have a schematic or data display that you want to have easily available from any workspace. Just use the File>Save As Template from the Data Display or Schematic window and save in the user library. I like adding a date stamp in case I need to keep track of more then one version. The user templates are stored in the default workspace directory path $HOME\hpeesof\circuit folder if you need to manually move them to a new ADS installation.

      Let us know which one of these features you find the most powerful for your needs, none of them require closing the existing workspace :). We love tgetting feedback and hope that the flexibility of ADS provides a solution for you.

    Cadence schematic/layout behave similarly, with added benefit of showing edits “live”.
    In text editing, xemacs also behaves the same way, while Excel – unlike Word – notifies/permits one to edit a “Read-Only” copy in memory.

    I’d say a useful feature to those aware of their edits.

    • Colin Warwick

      Thanks! As the video clip demonstrates, our edits show up live too. By the way, ADS since ADS 2011 is based on an interoperability technology called OpenAccess that Cadence donated to Si2. The workspace/technology library/cell/cell view hierarchy is one visible manifestation of the underlying OA database.
