Abstract Systematic defects due to design-process interactions are a dominant component of integrated circuit (IC) yield loss in nano-scaled technologies. Test structures do not adequately represent the product in terms of feature diversity and feature volume, and therefore are unable to identify all the systematic defects that affect the product. This paper describes a method that uses diagnosis to identify layout features that do not yield as expected. Specifically, clustering techniques are applied to layout snippets of diagnosis-implicated regions from (ideally) a statistically-significant number of IC failures for identifying feature commonalties. Experiments involving an industrial chip demonstrate the identification of possible systematic yield loss due to lithographic hotspots.

The use of unsecure foundries has allowed and is still providing a pathway for counterfeit microelectronics into U.S. defense systems. As a result, the Warfighter has been put at risk and a solution is needed. To counter this dilemma, this study looks into the feasibility of creating a Department of Defense (DoD) - wide design cloud that would provide circuit designers with a more secure and economical way of designing and fabricating circuits. The design cloud would include secure communication to trusted foundries along with needed circuit design software. Factors such as security, costs, benefits, and issues are taken into consideration in determining whether the use of the cloud would actually aid the integrated circuit design process.

Vlsi Floorplanning

The complexity of any integrated circuit pushes the researchers to optimize the various parameters in the design process. Usually, the Nondeterministic Polynomial problems in the design process of Very Large Scale Integration (VLSI) are considered as a Single Objective Optimization Problem (SOOP). However, due to the increasing demand for the multi-criterion optimization, researchers delve up on Multi-Objective Optimization methodologies to solve a problem with multiple objectives. Moreover, it is evident from the literature that biologically inspired algorithm works very well in optimizing a Multi-Objective Optimization Problem (MOOP). This paper proposes a new Lion’s pride inspired algorithm to solve any MOOP. The methodologies mimic the traits of a Lion which always strives to become the Pride Lion. The Algorithm was tested with VLSI floorplanning problem wherein the area and dead space are the objectives. The algorithm was also tested with several standard test problems. The tabulated results justify the ruggedness of the proposed algorithm in solving any MOOP.

Mechanical design education focuses on teaching students with fundamental design theory and methodology. Educators systematically introduce design theories, processes, and tools to help students solve design problems. Companies and professional organizations expect that students will be equipped with basic understanding of the engineering practice, and be able to effectively perform independently and in a team environment. Senior capstone design courses, particularly with industry sponsored projects, are widely used to satisfy both education and professional needs of students. This paper presents an education system, which can further facilitate students to acquire design skills in a real-time collaborative, and practical environment. The web-based system helps student teams to: (1) specify the design process for their team projects, (2) organize and distribute tasks among different team members to simulate industry design environment, and (3) get instantaneous access to models, analysis, etc. related to their design. The developed web-based system also contains a knowledge-base that provides students with instructions to setup the design process for projects, and to perform different design tasks. A virtual design organization is created in the system, which is managed by students. In this paper different components of the web-based design education system are presented.

Error Proofing

Error or mistake is occurred in such away that causing product malfunction, machine not working, process produce defective. All of these affect the quality and productivity, further more will increase cost of production.Many aspects can create error, such as human, design, process, raw material, method and environment. A lot of effort put in place to prevent or eliminate error. Detection by inspection is old method applied in industry. Detection can be applied pre production or post production. Both of method has their own advantages. Inspection prior production will ensure the input are free from defect, while inspection post production is to prevent defect escape to customer.In many industries nowdays, inspection still being carried out by human. This type of inspection has been affected by human capability which is very hard to be consistent at all time. In Integrated Circuit Assembly manufacturing, some problem may happen due to wrong orientation and or misalignment of production part. This research is carried out in one of IC assembly manufacture in Batam.

Logic design and verification is the frontend of ASIC (Application Specific Integrated Circuit), and is a very important design part during the design process of ASIC. A Verilog HDL design case－2×2 SDH digital cross-connect matrix is provided to illustrate the entire design process including logic-level description, verification and synthesis based on the frontend tools of Synopsys. After that a gate-level netlist conforming to the design requirements can be obtained.

Manual Tasks

While the design of digital integrated circuits (ICs) is largely automated, the design of analog/ mixed-signal (AMS) ICs is still dominated by manual tasks. One of the biggest obstacles to further automation is the large number of constraints that have to be taken into account during AMS IC design. They are derived both from the specifcation and during the actual design process and must be fulflled before production of the IC can begin. The aim of this work is to present our fndings regarding the formalization of constraints and their propagation within the design hierarchy in order to make them visible and verifable in all relevant cells. Constraints are integrated into the AMS IC design process so that they can be considered at all stages of the design. Our research enables the integration and consideration of constraints in all types of design tools—not only for AMS IC design, but after generalization for any design process.
