Incremental Control Techniques for Layout Modification of Integrated Circuits

Abstract

Analog layout is created in integrated circuits (IC) computer aided design (CAD) environment and during realization requires a lot of modifications of database objects. Because database objects modification is time consuming, then any improvement and simplification of modification flow in IC CAD environment can increase layout productivity. A proposed new modification concept can speed-up layout work and is very intuitive and easily put into practice.In advance, it allows to apply modern gesture tracking devices for control. By simplifying control of layout object modifications, the productivity of analog layout creation has been improved in the range of 23% to 66%.
