overlapping stretch handles - stretch both with one command

caver456

If you place two fets next to each other such that they share a diffusion terminal with just one row/column of contacts (or any other partially-overlapping pcell situation), you will have two stretch handles in the exact same location.  Stretching the metal of that shared diffusion terminal now requires two stretch operations.  Is there a way to do it in just one stretch operation?  Certainly not a massive time-saver, but, if you use it often enough, it adds up.  Thanks

  • Hi,

    try making the stretch (stretch drawing) layer selectable so that you can draw a box around the overlapping handles and grab both, then the stretch will apply to both.

    Best regards,
    Lawrence.
  • hmm, I made 'stretch drawing' valid and selectable, and stretch handles displayed, and all the selectable checkboxes enabled in the Objects panel, but the handles aren't selectable. Ideas as to what I'm missing?
  • I also tried making y0 drawing valid, visible, and selectable; no luck
  • Are they visible? Did you try Options -> Display -> Stretch Handles ? They need to be visible to be selectable.
  • yes, sorry, by 'stretch handles displayed' I meant that they are visible as the small yellow diamonds. I've read through the doc sections on 'difficulty selecting stretch handles' and none of that seems to make a difference. I do stretch them individually all the time with no problem, but infix is on so I just put the mouse over the handle and hit the bindkey for leHiStretch. I have not tried to select them until now (by drawing a rectangle around them).

  • I personally hate stretch handles - this is one of the many usability challenges with them... you don't seem to be able to area select the handles during a stretch. I think this may have worked in the past...

    Anyway, in IC617 ISR8 (and ICADV123) a new cdsenv variable:

    envSetVal("rod" "stretchDuplicateHandles" 'boolean t)

    was added - if you turn this on (to t) then you can area select the handles and it stretches them together. If they're on top of each other, you still need to area select them during the stretch to enable this (from my experiments).

    Was quite surprised to find this option!

    Anyway, my preference nowadays is to use the fluid protocol in PCells to give far more powerful control over interactive PCell edits (PCell Designer makes this easy to create). That's by the by though if you have existing PCells!

    Regards,

    Andrew.
