    How to reuse the hierarchical block? Reply

    Hello, everyone.

    I am now learning the CAPTURE's complex hierarchical design structure and I am using the software version 9.1. I am now encoutering a confusing problem. My problem is same as the author of the theme:http://www.chronology.com/forums/ShowPost.aspx?PostID=23229

      That is I want to reuse the descend schematic of a hierarchical block(suppose named A) many times, because there are many similar circuit blocks in my design. Firstly I creat a hierarchical block named A and complete the descend shematic of it. But when I make a copy of the hierarchical block A, I find that the reference designator of all the components in the descend schematic are the same between the copy and A. And when I change the componet reference in the descend schematic of either A or the copy, the other change at the same time. This makes the problem that A and its copy refers to the same circuit block but not two similiar one.
      I have read the help files of the software very clearly, but can't get the answer.
    Wishing for your reply.Thank you.

    If you have more than one copy of a hierarchical block in a design, the design is called a "complex hierarchy", the design will have changed to "Occurrences" mode and the annotation will be stored in the Occurrences properties. Tools>Annotate, select "Unconditional reference update" will correctly annotate the design. Use Edit>Properties on the part(s) and modify the properties in the "yellow" rows or columns as required to change the Occurrences properties, changing the visibile properties will affect ALL of the occurrences.

    Thank you very much, oldmouldy!

    With your help, I have solved my problem now. And I think the key point is that I hadn't understand the definition of "occurrences" in complex hierarchy. So I must set tool->annotate->mode to "update occurrences", to get different reference designators for the corresponding components in the different occurrence.
