Headers in Macro file

by Paul - 21 Jul 2009, 22:35 CEST

Can c++ header files such as:

#include<math.h>

be implemented in LayoutEditor macros?

by Juergen Thies - 22 Jul 2009, 8:03 CEST

Including files is possible. But there will be no access to external libraries, because the macro cannot be linked to it. So including header files will not work.

You can access math features though the class math. Example:

double d=math::sin(1.2345);

I am trying to use the rand() function which I believe resides in the stdlib. I have already tried

int X = cstdlib::rand();

and

int X = stdlib::rand();

How would I go about using the rand() function?

(neither of the above tries worked error : unknown identifier)

The current release does not support the rand() function. I will add it with the next release.

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.
