Matching components and nets with VXL

Hi andrew and all,
With VLE we can put the components and nets inside a "half cell" and
instantiate them in the toplevel so that the components and nets are
matched and symmetrical w.r.t. a line.
But we can not do this with VXL, because the VXL connectivity engine
can not understand the half cell technique.
So, whats is the suggested way for laying out things differentially
with VXL.

Suresh

 

David, It is a separate level of hierarchy inside which all the
differential components and routings resides. The toplevel would contain
two instances of these half cells. They would be placed in such way that
one looks like the mirror image of the other.

VLE does not have to know what these half cells are since it does not do
any connectivity based stuffs. For VLE half cell is nothing but an instance.

Thanks for the response,

 

David, But the schematic would not have the half cells. My question not
that how to make vxl understand the "half cell", but how to achieve same
kind of matching without using half cells.

Thanks for your time.

Use the cloning functionality in VXL.

Andrew, Thanks.
