This operator is short-circuiting: if the first operand is false, the second operand is not evaluated.įor the built-in logical OR operator, the result is true if either the first or the second operand (or both) is true. Otherwise, the result is false.įor the built-in logical AND operator, the result is true if both operands are true. If the operand is not bool, it is converted to bool using contextual conversion to bool: it is only well-formed if the declaration bool t(arg) is well-formed, for some invented temporary t.įor the built-in logical NOT operator, the result is true if the operand is false. Builtin operators & and || perform short-circuit evaluation (do not evaluate the second operand if the result is known after evaluating the first), but overloaded operators behave like regular function calls and always evaluate both operands.However, in a user-defined operator overload, any type can be used as return type (including void). All built-in operators return bool, and most user-defined overloads also return bool so that the user-defined operators can be used in the same manner as the built-ins.The keyword-like forms ( and, or, not) and the symbol-like forms ( &, ||, !) can be used interchangeably (see alternative representations).Just use you favorite vector font.Returns the result of a boolean operation.īool T :: operator & ( const T2 &b ) const īool operator & ( const T &a, const T2 &b ) īool T :: operator || ( const T2 &b ) const īool operator || ( const T &a, const T2 &b ) The LayoutEditor can do this with just one mouse click. ![]() A conversation to real polygons had to be done before. Text labels are usually ignored during the tape out. A transfer to the LayoutEditor source code is possible with Minimal changes. The macro are written in the most common language C and can be integrated in the menu structure. This makes the macro creating very simple and reduced the time to learn commands. But the LayoutEditor has the possibility to record macro from the user interface like some office programs can do. Macros or scripts are already standard to many programs. The most important handling functions like zooming and scrolling are integrated in each feature and need not to be called separately. This virtual contrast is solved with an extensive use of shortkeys and mouse buttons/keys Combination together with clear visibility of this combinations. The LayoutEditor is crossplatform compatible and runs on Windows, Linux, Mac OS X and much more plattformsĪ clever worked out user interface provides a outstanding usability on the one hand and a high productivity on the other hand. ![]() LEF, DEF, Alliance, Lasi file can be imported. Also Oasis (Open Artwork System Interchange Standard), DXF, CIF (Caltech Intermediate Form) and Gerber (RS-274X) are full supported. The Calma GDSII file format is used as the primary file format. It has sophisticated functions like all angles, Font Generator, macros, boolean operations, design rule checker, netlist driven layout and LVS. As well as it is suitably for Multi-Chip-Modules (MCM), Chip-on-Board (COB), Low temperature co-fired ceramics (LTCC), Monolithic Microwave Integrated Circuits (MMIC), printed circuit boards (PCB), GDS Editor thick film technology, thin film technology. LayoutEditor an free GDS Viewer is a program to design and edit layouts for MEMS/IC fabrication.
