symbolic layout editor


graal [-l file_name] [-scale n] [-debug] [-xor] [-install]


Graal is a hierarchical symbolic layout editor. All functionnalities can be accessed through different menus. Among them exists a design rule checker performing verifications inside a user defined window. Graal works under Motif and X11r6. When entering Graal, the main window appears and shows 7 different menus on the top bar.These menus can be entered by simply clicking on the mouse left button. The main window is sensitive to the mouse, and the mouse wheel can be used for scrolling up and down, left and right when <Shift> is pressed during wheel movement, and zooming in and out, when <Ctrl> is pressed while turning the wheel.

Below is given the description of graal's menus.
