<a name="sparse_array_limit"/><h2>"sparse_array_limit" - Gets or sets the sparse array singularization limit</h2>
<keyword name="sparse_array_limit"/>
<p>Usage:</p>
<ul>
<li><tt>sparse_array_limit(limit)</tt></li>
<li><tt>sparse_array_limit</tt></li>
</ul>
<p>
In deep mode, array instances with a bad ratio of overall bounding box area
vs. actually covered area, induce a performance penalty, because their bounding
box is not longer a good approximation for their footprint.
The "sparse array limit" defines the ratio of array instance bounding box area
vs. sum of bounding box areas of the individual instances, above which the array
is resolved into single instances.
</p><p>
Use this method without an argument to get the current value.
</p><p>
By default, this feature is off (the sparse array limit value is negative).
If your design uses many arrays with a bad coverage, you can set the sparse
array limit to a value of 10 for example.
