How to Achieve Good Parameter Optimization Using The New Methodology in UTMOST III Optimizer

Optimization is the task of finding the absolute best set of admissible conditions to achieve your objective, formulated in mathematical terms. The goal of optimization is, given a system, to find the setting of it's parameters so that to obtain the optimal performance. The performance of the system is given by an evaluation function. Optimization problems are commonly found in a wide range of fields, and it is also of central concern to many problems.

How to extract BSIM4 parameters using UTMOST III

The BSIM4_FI routine in UTMOST III MOS module should be used for data collection and BSIM4 SPICE model parameter extraction. The BSIM4_FI routine features are similar to the BSIM3_MG routine. The BSIM4_FI routine will collect four types of measured data curves from each device.

Connectivity Options for DRC Spacing Check Operations in Savage

An IC layout has to satisfy many technological design requirements. One of these is spacing, i.e., a layout object has to be separated from another one by some minimal distance. In addition, any spacing requirement (e.g. minimal distance between layout objects) varies depending on the particular features of the layout objects, e.g. the layer the objects belong to, the purpose of these objects, etc.

Optimal Packing of Orthoblocks For ULSI Floorplanning

Virtually all latest and prospective enhancements of Expert Layout processor (for example, semi-automatic floorplanning) are based on sophisticated geometrical models. In some cases some advanced mathematical research is necessary to develop efficient algorithms. This article is devoted to the problem of optimal packing of orthoblock which is originated from several areas of VLSI design automation.

Hints, Tips and Solutions for Expert Layout Editor

If I try to close a project, Expert gives me a prompt: "Save changes in a project?", but I remember that I didn't do any editing of cells. When can be the reason. The second question is: how do I know which cells were modified?
