wafer map plot

[Y3G]

Hi ,

I a, looking for a "wafer map" plot options 2D where I can simply upload data and present the distribution of e.g. Touchstone file values on a wafer.

Thanks

Kind of sounds like an intensity plot. Do you have a sample picture similar to what you want or a website link??

Hi,

Something like this probably: (see attachement) or similar

Thanks

Hello,

you mean something like the pic, that I have attached in this thread:

You could also do something by drawing colored boxes in a picture indicator. This is in 7.0 format.

You could also use a 2D array of color box controls or indicators.

Hi,

Thanks for all and the fast reply.

The last one seems to be the most convinient...

I assume I will use the  matrix indexes as x-y coordinates of the wafer.

But how and where do I add the Intensity (-z-value) in different color grade? Those for example will be the dB values with a different spread of colors.

Thanks

includes a link to the "Obfuse Code" example i posted.

I believe it can be quickly adapted to accomplish the task at hand.

The color is a U32 value that is written into the 2d array at each element. You could setup a master array of color boxes for each bin. Then use the bin value to index the correct color out of this master array. Then use replace array element to insert this new color value into the 2D array.

Hi,

I have progressed so far but stucked on the "old" issue how to fill in a circle within the array, so it looks like a wafer map. What will be my approach? Having two for-loops (one for culomn, one for row) that de-/increase the index of the array (like the mathematical approach of drawing a circle U=2*pi*r)??

What if I'd like than later point with the mouse on one array bin (=wafermap) and having its value and index on real-time, how do I do this?

Thanks
