Documentation of the macro programming language

by anonymous - 5 Mar 2009, 16:28 CET

Having played around a little with LayoutEditor, I'm very interested in learning more, in particular, about the scripting language.

I've tried to "reverse engineer" the language by recording macros but it is not conducive to learning about how to select elements etc.

I end up with code looking like this:

layout->drawing->point(23333082,42144247);
layout->drawing->cSelect();

which is pretty much useless for generalization.

How can I learn more about this and learn proper methods for scripting (with cells) in LayoutEditor.

Great software by the way!

The scripting language is basicly a C++ code with some additional LayoutEditor spezific classes. A basic introdution can be found here.

Selecting/deselecting is possible via the drawingField class. It is accessible via 'layout->drawing->...[command].

Some other usefull commands are in the class cell. The current displayed cell is accessible via 'layout->drawing->currentCell->...[command].


There are also some example macros with comments shipped with the LayoutEditor.

Going on from the earlier question ...

What is the canonical way of doing the following:

layout->drawing->point(200, 200);
layout->drawing->point(-200, -200);
layout->drawing->box();
layout->drawing->selectAll();
layout->booleanTool->setA();
layout->drawing->point(0,0);
layout->drawing->point(100,0);
layout->drawing->circle();
// How to specify the right circle?
layout->drawing->cSelect();
layout->booleanTool->setB();
layout->booleanTool->AminusB();

I'd be nice to be able to do this in a less primitive way.

a more clear way would be:

cell *c=layout->drawing->currentCell;
c->addBox(-200,-200,400,400,105);
point center;
center.set(0,0);
c->addCircle(106,center,100);
layout->booleanTool->addLayerA(105);
layout->booleanTool->addLayerB(106);
layout->booleanTool->aMinusB();

Many thanks, I will try it out rightaway.

The LayoutEditor™ is a program to design and edit layouts for MEMS/IC fabrication and CMOS IC design .Designing these layouts require a high precision. In IC design a sufficient resolution and a possibility of a high scaling is required. The resolution of the LayoutEditor can be set in a wide range and is normally set to 1 nano meter. A higher resolution makes no sense due to atomar structures. With this resolution the LayoutEditor can draw elements up to 4 meters. In many IC design houses this is enough for IC/MEMS which extend usually less than 0.1 meters. The productions of MEMS/IC is done in many layers. For each of these physical CAD layers a belonging layer had to exist in the drawing. Additional logical layers are required for describing/naming purpose. So a lot of layers are needed. By default the LayoutEditor is limited to 128 layers. But it can easily be adjusted, if more layers are required. IC Designs often contain a plenty of repeating structures. Essential for micro fabrication of these designs is therefor a hierarchical design. This means, that the complete repeating structure only exists once in a single cell. These cell is then referred multiple times in the main drawing.
Beside the above mems packaging mentioned IC design fundaments it is important to have sophisticated functions to handle all drawing elements. The layout handler has all required functions: all basic design functions, all angle elements, boolean operations, macros, fontgenerator, design rule checker, mems tools, supported format: GDSII, DXF, OASIS, CIF.
