<H2>flatten</H2>
<HR>
Flatten edit cell into the indicated destination cell.
<HR>
<H3>Usage:</H3>
<BLOCKQUOTE>
<B>flatten</B> <I>cellname</I> [<I>option</I>] <BR><BR>
<BLOCKQUOTE>
where <I>cellname</I> is the name of a cell definition to be
created, and into which the flattened geometry will be placed.
<I>option</I> may be one of <B>-nolabels</B>, <B>-nosubcircuit</B>,
or <B>-novendor</B>.
</BLOCKQUOTE>
</BLOCKQUOTE>
<H3>Summary:</H3>
<BLOCKQUOTE>
The <B>flatten</B> command creates a new cell with the indicated
name, then flattens the hierarchy of the current edit cell and
copies the result into the new cell. <P>
The options allow selective flattening, as follows:
<DL>
<DT> <B>-nolabels</B>
<DD> Prevents magic from copying labels into the flattened cell.
Otherwise, magic flattens labels by prepending the cell
hierarchy to each label as it copies it into the flat cell.
<DT> <B>-nosubcircuit</B>
<DD> Prevents magic from flattening cells declared to be subcircuits
(by the presence of ports in the cell). These cells are
retained as subcells in the flattened version.
<DT> <B>-novendor</B>
<DD> Prevents magic from flattening cells that are vendor cells,
that is, cells that are generated by reading GDS using the
<B>gds readonly</B> option, or which have the appropriate
property values set.
</DL>
Note that <I>cellname</I> is a top-level cell but is not displayed
or saved subsequent to the <B>flatten</B> command. The usual
procedure is to follow the command "<B>flatten</B> <I>cellname</I>"
with "<B>load</B> <I>cellname</I>", to view the new flattened
layout.
</BLOCKQUOTE>
<H3>Implementation Notes:</H3>
<BLOCKQUOTE>
<B>flatten</B> is implemented as a built-in command in <B>magic</B>.
