resize drawing

I am writing in hopes that you can help me resolve an issue. I have not been able to find an answer on any help or forum page.

The problem is that once I complete a schematic sheet, if the circuit occupies a quarter of the sheet, there is no way to scale the drawing to the printed page. Consequently, the circuit is a small blob in the corner of the sheet with unreadable information. Is there a way to resize the drawing sheet so that the circuit scales to fill the sheet and print accordingly?

Thank you,

Tom Mazzola

    Yes, the BDF files are not supported, but you can always zip the file, because ZIP files are supported.

    Thanks zizka, that worked just fine. What did you do? Have you seen this problem before?

    Hi zizka,

    I need to know what you did to fix the resizing problem. I have several other schematic sheets with the same issue.

    Thanks

    Hi, it seems that you had some assignments or parameters at the IO pins which were incorrectly removed, so there were some residues in the BDF file. There were objects (annotation_block) which did not display in the editor, so you were not able to select them nor delete them, but they were occupying some place. So the editor did fit the schematic correctly to the display, there were just some symbols that you were not able to see.

    I've deleted them manually from the BDF file.

    Hi zizka,

    I have many schematic sheets with the same problem, so it appears that I am creating these invicible objects unknowingly. I still need your help. Would you mind sharing the steps you took to delete these "things" from my schematics, some sort of instructions so that I can proceed with my designs? How do I delete them manually?

    Thanks.

    if you do a diff on the two .bdf files, you will see he deleted each line that contained annotation_block. you should be able to write a script to kill each of these lines

    OK, I guess that means that the Quartus II GUI doesn't have an easy way to accomplish this... bummer. I may be able to see the differences between my file and his, but how do I eliminate the extra junk I can't see on my drawings? Would you mind helping to create this script? Hardware is my forte, very weak with firmware/software.

    for what its worth, i opened both the original and edited .bdf files, and print preview always shows a small schematic instead of full page

    the following sed command will edit your original .bdf to zizka's edited .bdf:

    sed '/annotation_block/d' old.bdf > new.bdf

    sed is probably included in the Nios II EDS if you open up a Nios II command shell

    i don't know the consequences of deleting all of the annotation_block lines
