A Constraint-Driven Placement Methodology for Analog Integrated Circuits
نویسندگان
چکیده
A new constraint-driven methodology for the placement of analog IC's is described. Electrical performance speciications are automatically translated into constraints on the layout parasitics. These constraints and the sensitivity information of the circuit are then used to control a Simulated Annealing-based placement algorithm. At each step of the annealing a fast check on performance degradations is performed to guarantee that the tool has the necessary robustness.

Top-Down, Constraint-Driven Design Methodology Based Generation of n-bit Interpolative Current Source D/A Converters
To accelerate the design cycle for analog circuits and mixed-signal systems, we have proposed a top-down, constraint-driven design methodology [1]. In this paper we present a design which demonstrates the two principal advantagesthat this methodology provides– a high probability for first silicon which meets all specifications and fast design times. We examine the design of three different 10-b...

To accelerate the design cycle for analog circuits and mixed-signal systems, we have proposed a top-down, constraint-driven design methodology [1]. In this paper we present a complete design flow to illustrate this design methodology as it applies to the design of a second order sigma-delta (Σ-∆) analog-to-digital (A/D) converter. We start from its performance and functional specifications and ...
متن کاملAn Improved Standard Cell Placement Methodology using Hybrid Analytic and Heuristic Techniques
In recent years, size of VLSI circuits is dramatically grown and layout generation of current circuits has become a dominant task in design flow. Standard cell placement is an effective stage of physical design and quality of placement affects directly on the performance, power consumption and signal immunity of design. Placement can be performed analytically or heuristically. Analytical placer...
متن کاملEvent-Driven Electrothermal Modeling of Mixed-Signal Circuits
This paper describes a novel modeling methodology for electrothermal effects in large mixed-signal circuits. It is accomplished by developing analog event-driven electrothermal and thermal models in an analog hardware description language (AHDL). The large-scale mixedsignal circuits represented by the analog event-driven models can be analyzed more efficiently than using standard analog models.

In this paper, we present a complete chip design method which incorporates a soft-macro placement and resynthesis method in interaction with chip floorplanning for area and timing improvements. We present a performance-driven soft-macro clustering and placement method which preserves hardware descriptive language (HDL) design hierarchy to guide the soft-macro placement process. We develop a tim...
