Introduction

The Qckvu Image Server Library [QISLib] is a powerful GDSII/OASIS database server that enables a client calling program to display and manipulate GDSII/OASIS data using a simple set of calls. As GDSII and OASIS files grow larger, many software developers are discovering that their own GDSII routines are no longer able to deal effectively with these large files -- they face the need to completely rewrite GDSII readers to handle files of 10,20 and even 50 GB.

QISLib can be used as a "toolkit" and eliminates the need to deal with the problems associated with opening and randomly accessing such large files. The OEM can focus on his core expertise and leave the heavy data manipulation to QISLib.

Application Notes

This app note describes memory use when opening large GDSII files and the various options that can be used for controlling memory footprint.

This app note describes how to use QISLIB to fracture a layout (in GDSII or OASIS) into trapezoids.
