Layout editor: quick align "Move/Stretch" mode deprecated in ICADV?

dontpanic

Hi! The "Move/Stretch" mode is not available in my layout editor (L) in ICADV 12.3.  Here's a comparison of what I see in IC 6.1.6 (28nm PDK, left) and ICADV 12.3 (16nm PDK, right):

Moreover, the Layout Editor L documentation for ICADV 12.3 still mentions this mode (p.1086 of the user guide)... is my setup (or PDK) broken? has this mode been deprecated?

Thanks in advance for any help!

Regards, Jorge.

    Hi Jorge,

    It's just a change in terminology as part of the form simplification and use of progressive disclosure. Move/Stretch is the default, and turning on "Copy Reference" is the same as the old "Copy" choice (so if it's off, it's Move/Align). See this very recent thread in this forum: Bind key for setting to "copy reference" mode in the "Quick Align" window. So nothing has been deprecated in this case.

    Regards,

    Andrew.

    Hi Andrew, thanks for your prompt reply! The problem is that for some reason the behavior is not as expected. Indeed, upon opening the tool the mode seems to be "Move/Stretch":

     leGetEnv("quickAlignMode")  

     "MoveOrStretch"   

    but if I do try to quick-align e.g. the vertical path segment highlighted in the figure I posted, the full path is moved, instead of stretching the horizontal segment to align the vertical one to the chosen reference (target) edge.

    Any ideas on what could be causing the problem? 

    Thanks and regards, Jorge.

    Hi Jorge,

    Did you pre-select the entire wire before doing the quick align? If so, that would be expected. If you want to pre-select and only want the one segment, you can either use F4 (or Options->Selection) to go into partial select mode, or on Options->Selection turn off "Spine" which controls whether it will select the entire wire when in full select mode, or just the segment you're over.

    If that's not it, can you describe precisely what the segments look like and what you've selected in advance, which select mode you're in (maybe a screenshot of the Options->Selection form) and where you clicked and when. If that's not too much to ask!

    For example, for me - if I didn't pre-select anything, I could click on the segment of the wire I wanted to stretch, and then click on where I wanted to align it to.

    Regards,

    Andrew.

    It was the selection mode! (I was totally unaware about its existence--sorry!) Switching to partial-selection mode with F4 yielded the desired behavior Smiley

    Thanks so much for your help, Andrew!

    Enjoy the weekend, 

    Jorge.
