Matrix Visualization

Multi-objective optimization and multi-criteria decision aid applied to the design of 3D-stacked integrated circuits

“…Design complexity and design software A large number of systems have been implemented using the 2D technologies which means that current tools can cope with 2D design complexity even if they show more and more their limits [12,19]. As for 3D-SICs, the increased complexity can be tackled by developing adapted software [5].…”

“…The current design flows, which are not developed to cope with the needs of 3D-SICs, may thus need improvements to be able to deal with the increased complexity [12,19].…”

“…They have also been used conjointly with other visualisation tools such as scatterplot matrices and parallel coordinates [9]. In all of these contributions, the authors all agree on the fact that reordering rows and columns in data tables is an essential part in the graphical exploration of quantitative or qualitative data [10][11][12]. …”

“…Also, they are sequential in nature as certain parameters are fixed at certain stages in the flow, which can lead to locally optimal solutions that are far from global optimums so this requires time consuming (hence, costly) iterative processes to adjust these parameters. Since the 3D technology is even more complex than the 2D, it is necessary to improve the current design flows by developing design exploration [12,19].…”

“…One of the solutions to face this problem is to develop high-level tools which can quickly explore design spaces and give early and reasonably accurate performance estimations based on physical prototyping of the 3D circuits [12]. In addition, performance estimation/optimization and the selection of the most-suitable solutions usually implies to take several objectives into account (e.g.…”
