axlDBAddProp overwrite difference layer setting

nightingale

Hello:

I use axlDBAddProp to add Dyn_Clearance_Oversiza_Array for each layer ,the rule is first check the thermal width for pin on all layers,the width can be difference on difference layer.After get width for one layer ,I use axlDBAddProp to add the Dyn_Clearance_Oversiza_Array,but when I added this properties for another layer ,The pre-layer property overwrited.:

For example

I first using  axlDBAddProp(a list("DYN_CLEARANCE_OVERSIZE_ARRAY" "TOP:0.5"))

then I checked bottom layer thermal clearance need to be 0.6mm ,so axlDBAddProp(a list("DYN_CLEARANCE_OVERSIZE_ARRAY" "BOTTOM:0.6")), After add property successfully ,the Top side clearance missing.

Could you proposal how to keep the pre-property ?

By the way ,I can't add all layer properties at one time as I need to check width layer by layer.

    axlDBAddProp can have a nasty effect on your dbids. Try using axlDBRefreshId after each add.

    Hello:

    Thanks for you quickly response,it is not working even I add axlDBRefreshId after each add. Only the last properties affect.

    I struggle to understand what you are trying to do. The property DYN_CLEARANCE_OVERSIZE_ARRAY accepts only an integer as a value according to the documentation:

    The DYN_CLEARANCE_OVERSIZE_ARRAY property, attached to shapes, filled rectangles (frectangles), pins, vias, or clines, overrides the value in the Oversize values field in the Clearancestab in the Shapes Instance Parameters dialog box and increases the clearance around the specified element. The value is a positive integer. Negative integers are not supported.

    You can apply this property with different values to each layer in a design.The layers includes outer layers, inner plane layers, inner signal layers, and individual layers

    For example, if the value in the Oversize values field is 6, and the value of the DYN_CLEARANCE_OVERSIZE_ARRAY property is 4, the total clearance is 10.

    Ok. I see not that the documentation is misleading. However, to assign this property correctly to an object, it needs to be assigned only once. The resultant value looks like this:

    DYN_CLEARANCE_OVERSIZE_ARRAY = TOP:0.5 MM;T0.6 MM

    So, to add a value you will have to concatenate the values. eg axlDBAddProp(list(objDBID), list("DYN_CLEARANCE_OVERSIZE_ARRAY", "TOP:0.5;T4:0.6"))

    Hello Dave:

    I got the answer ,before I add properties ,I get the properties first,and append1 the new value to the properties
    but after that I got and warning:
    W- *WARNING* (axlDBAddProp): Not a floating point number! - ("INT2:0.5"  "TOP:0.5"  "INT1:0.5" "BOTTOM:0.5"
    how do i convert all these value to float number ?  I know atof can use converts a string into a floating-point number,but here is no only a value.
