Layout view of a simple CMOS operational amplifier. In integrated circuit design, integrated circuit (IC) layout, also known IC mask layout or mask design, is the representation of an integrated circuit in terms of planar geometric shapes which correspond to the patterns of metal, oxide, or semiconductor layers that make up the components of the integrated circuit.
India has the Semiconductor Integrated Circuits Layout Design Act, 2000 for the similar protection. Japan relies on "The Act Concerning the Circuit Layout of a Semiconductor Integrated Circuit". Brazil has enacted Law No. 11484, of 2007, to regulate the protection and registration of integrated circuit topography.
Digital design focuses on logical correctness, maximizing circuit density, and placing circuits so that clock and timing signals are routed efficiently. Analog IC design also has specializations in power IC design and RF IC design. Analog IC design is used in the design of op-amps, linear regulators, phase locked loops, oscillators and active ...
In integrated circuit design, physical design is a step in the standard design cycle which follows after the circuit design.At this step, circuit representations of the components (devices and interconnects) of the design are converted into geometric representations of shapes which, when manufactured in the corresponding layers of materials, will ensure the required functioning of the components.
In electronic design automation, a floorplan of an integrated circuit is a schematic representation of tentative placement of its major functional blocks. In modern electronic design process floorplans are created during the floorplanning design stage, an early stage in the hierarchical approach to integrated circuit design .
In electronic design, a semiconductor intellectual property core (SIP core), IP core or IP block is a reusable unit of logic, cell, or integrated circuit layout design that is the intellectual property of one party.
Initially, GDSII was designed as a stream format used to control integrated circuit photomask plotting. Despite its limited set of features and low data density, it became the industry conventional stream format for transfer of IC layout data between design tools of different vendors, all of which operated with proprietary data formats.
The Semiconductor Chip Protection Act of 1984 (or SCPA) is an act of the US Congress that makes the layouts of integrated circuits legally protected upon registration, and hence illegal to copy without permission. It is an integrated circuit layout design protection law.
