The Check In Foreground Button: Check Region or Cell
The Check In Foreground button in the DRC Menu 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.cellname'' 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.
Similar checking can be performed in the background with the Check In Background button.
