Skill code for effective width of power shape?

BW202408289157 10 months ago

Hello,

Has anyone developed SKILL code to calculate the effective width of a power shape?

This would be useful for cases where the power shape needs to have a specific width such as 300mil to handle the proper current requirements, but there are vias that interrupt the shape that take away from the overall width making it maybe 200 mil in some areas instead.

The SKILL program would calculate the width of the power shape at these highly via populated areas and return the values in a text file or somehow highlight it on the board for the designer.

New to skill programming so if this something someone could help me write or write it for me that would be great!

Thanks

This sounds interesting and (in principle) simple enough to implement but can you share an image/example of what you want the code output to be?

So this is kind of an example of what I would like the program to do. Either the program or the user would draw a line across the power shape as seen in the picture above. It would then use the measure tool to find the distance the edge of the shape/via to the next edge, ignoring the via width in the total measurement. After doing each calculation, the program adds the distance to a variable. The code output would then simply just be the final value of that variable which would be the effective power shape width.

I think it would be easiest for the user to make the line themselves and then when running the program they click on the line and it will output the effective width of it.

Does that answer your question?

Yes. In power shape we need to avoid the void and check the width of shape. Check the width by horizontally and vertically depends upon the shape. If anybody give assistance to write the skill, It would be great.

Why would you avoid the width of the void?

That's what is reducing the amount of copper for current distribution...
