How to use LSelection_Merge() for UPI in L-Edit?

[DragosVok]

Hello,

I'm trying to write a c code for a macro to generate a differential input stage. I read the L-Edit manual for UPI, but I don't know how to merge several boxes on the same layer.

Example: I have 3 boxes of poly which overlaps. Which is the syntax for doing this?

Thank you!

OK...I shall answer myself at this question. There was a silly mistake. The syntax is:

LSelection selected;
LSelection_SelectAll(); // here you can select only one type of layer - see
Selection Functions
selected = LSelection_GetList();
LSelection_Merge();
LDisplay_Refresh();

The problem was that I didn't write the last line and the display of the layout was not refreshed. After I added this line, the merge operation was shown.

The layout created by macro is flatten.
If you just layout the diff input pair, i think you can insert mos/bjt cell that will more usefull.
And you can create a tcell with parameter what you want, it will easy and usefull.
