Faizan Latif

Dear Sir,

i want the skill codes for the following

1) How to set Grid in layout from skill

2) When using path command,  when we click on a route with a net,  the LSW will change it layer to that particular  layer and draw path with that layer.

Thank You So much

  •  Faizan,

    By "grid" do you mean the drawn grid or the snap grid? If you look at Options->Display Options, are you talking about the Minor Spacing/Major Spacing, or the X and Y snap spacing?

    If you want to change them for the current window, it would be:

    hiGetCurrentWindow()->gridSpacing=2.0 ; minor spacing
    hiGetCurrentWindow()->gridMultiple=4 ; (you enter Major Spacing on the form, but it's specified on the window as a multiplier for the minor spacing - this would mean a major spacing of 8.0)
    hiGetCurrentWindow()->xSnapSpacing=0.01
    hiGetCurrentWindow()->ySnapSpacing=0.01

    If you want to set this in your environment as the default for new windows, then you'd use:

    envSetVal("layout" "gridSpacing" 'float 2.0)
    envSetVal("layout" "gridMultiple" 'int 4)
    envSetVal("layout" "xSnapSpacing" 'float 0.01)
    envSetVal("layout" "ySnapSpacing" 'float 0.01)

    Note however that if there are properties saved on the cellView, the library or the technology library, then these would win over the envSetVal settings.

    Not entirely sure what you're asking for the second question, and it may depend on the version used. It might be that you want to do:

    envSetVal("layout" "autoTapType" 'string "layer attributes")

    but as I said, it depends what you really are asking.

    Andrew.
