The Check In Foreground Button: Check Region or Cell
The Check In Foreground button initiates design rule checking on
a region or cell. The user is requested to point to the corners of a
rectangle defining the region to be checked. Simply clicking will
cause checking of the objects under the pointer. Holding and dragging
will cause checking of all objects which overlap the ghost-drawn
rectangle, when the button is released. If the user presses and holds
without moving the pointer for a brief period, the ghost-drawn
rectangle corner will be attached to the pointer, and pressing a
second time will complete the operation. Instead of a mouse button
press, pressing the Enter key will cause the entire area of the
current cell to be checked. All objects in the current cell and its
subcells which overlap the specified region are checked. Errors are
recorded in a file named ``drcerror.log'' which is written in the
current directory. Additionally, violating objects are marked, and
the error highlighted. During checking, button and key presses are
locked out, however pressing Ctrl-C will abort the checking.
