90 Degree Corner check

Is there a way to check for 90 degree corners in a Layout with DIVA?

thanks,

 

What do you mean by "corners" ?
Do you mean 90 degree angles ?

The command geomGetAngledEdge allows to select edges or shapes by
specifying their angles. Take a look to the Diva Ref. Manual.

The I don't want to check the orientation of the shape, but that the 4
corners are chamfered, not 90 degrees. I've tried the geomGetAngledEdge
command, and that just flags a shape that is oriented at 90 degrees,
not the corners. I've search the Cadence site for the Diva Manual, with
no luck, can you point me to the document.

thanks for the help,

 

Assuming you want to find angles that are 90 degree corners, use the drc
command to generate a small triangle where the inside angle of a corner
is 90 degrees or less. If you don't want the acute angles, add the
perp_only modifier, but it will run slower.
