Question on Mosaics

[New User ^_^]

Hi Everyone,

I have looked at different references of SKILL but still I am not sure
what mosaics is. It says "Arrays are created by dbMosaic objects ...
". So what is mosaics? Is it an array of instances or objects?

As I know, we can create simple mosaics by using dbCreateSimpleMosaic
or dbCreateSimpleMosaicByMasterName. But I am wondering why we need to
indicate the origin of the instance as well as the size of the array
(x_row & x_col) when using the above functions. Does it mean that we
put the instance in a particular position of an array? Don't we need
the row and column index?? It is very confusing that we need to
indicate the size of array but not the coordinate indexes!!

Thanks for your help!

as far as I know a mosaic is an array of *evenly spaced*
instances.
this means you specify the origin of the array (x0,y0) and spacing
between instances (dx,dy) and then, instance (m,n) of your array
is placed relatively to the origin at (x0+n*dx, y0+m*dy).

try creating a mosaic in Virtuoso by hand (Create->Instance, and
then enter values in the 'Mosaic' part of the options form, ie Rows,
Columns, deltaX and deltaY) and you'll see.

S. Badel, thank you for your answering!! It sounds that mosaic is not
that useful when we want to create different kinds of instances,
because we need to make a cell to place different instances first.

Anyway, thank you ^.^
