Mastering Digital CMOS Layout Design



  • Digital circuit design


IC Layout mask designer are in high demand right now and the specialized tool Microwind gives benefits to future design engineers and the instructors so that they can get a competitive edge in their careers by having skilled knowledge on CMOS circuits; which attracts the employers.

The fabrication of integrated circuits is based on the layout of patterned material-layers one on top of the other. Several such layers are not accessible to the circuit‟s layout-designer because they are required for isolation  or electrical contacts between the semiconductor device and the supporting interconnect structure. In order to get from circuit topology to the actual layout-topology, the designer should have a firm understanding of the representation of devices in a layout and also the ability to do the reverse, i.e. seeing a layout and having an idea of the corresponding circuit and therefore the circuit‟s function. Specialize software tools aid the designers in both of these directions.

Microwind is a friendly Windows-PC software-tool for designing and simulating microelectronic circuits at layout level. The tool features full editing facilities attractive views such as MOS characteristics, 2D cross-sections, 3D views, atomic views and efficient analog simulator. No SPICE or external simulator is needed. The analog simulator is built-in.
