Creating a magic ruler

Adhil
Hi All!!! 1. i have always found it tedious to draw a ruler to double check layout parameters such as diff overlap past poly, when doing testchip layout. i want to design a code where when i run my cursor over or close to a side of an object (at the same level or at a lower hierarchy), the side gets highlighted. 2. after clicking, the coordinates of the side gets selected and when i do the same to a side of another object, a ruler is drawn from the first side to the second automatically. 3. this eliminates the need to zoom in and drag and draw a ruler. 4. i have used the gravity option, but i find it insufficient. please your advise and codes are most welcome, i am looking into dbgettrueoverlaps and other related skill functions. adhil

  • If you are already clicking twice, then setup one of your mouse keys to be a ruler bindkey. The following example uses Ctrl-mouse2 (hold down the control key, and press your middle mouse button to start the ruler and then do the same to finish your ruler):

    procedure(myMouseRuler()
      let((infix)
        cond(
            (hiGetCurrentCmd(hiGetCurrentWindow()) == "Ruler"
                mouseAddPt()
            )
            (!hiGetCurrentCmd(hiGetCurrentWindow())
                infix   = hiGetCIWindow()->infix
                hiGetCIWindow()->infix = t
                leHiCreateRuler()
                hiGetCIWindow()->infix = infix
            )
        )
      ) ;let
    ) ;proc
    hiSetBindKey("Layout" "Ctrl<Btn2Down>" "myMouseRuler()")
    hiSetBindKey("Layout" "Ctrl<Btn2Down> EF" "myMouseRuler()")

    You can enhance this further by adding gravity. Put these two lines before the leHiCreateRuler:
                gravity = envGetVal("layout" "gravityOn")
                envSetVal("layout" "gravityOn"      'boolean t)
    And restore the previous gravity setting after the leHiCreateRuler:
                envSetVal("layout" "gravityOn"      'boolean gravity)
