Currently, most design rule checks (DRC) for VLSI circuits are run on CPUs with very few threads. The purpose of this project was to implement open-source software that performs bitmap- based DRC on both the CPU and on a parallel GPU and to measure the speedup.What appeared to be one ...
Unless otherwise mentioned,we assume that all dis-tances are euclidean distances. Let d(a,b) denote the euclidean distance between a and b.Let us consider the special case of the above problems that occurs in VLSI design rule checking.A generic instance of the problem may be speci,ed as ...
sign rule checking (DRC) is the process of checking if the layout satisfies the given set of rules. In a VLSI layout editing environment [8], geometric queries com- monly arise. However, the user often zooms to a part of the layout and is interested in queries with respect to ...
Design Rule Checking is a compute-intensive VLSI CAD tool. In this paper we propose a parallel algorithm to perform Design Rule Check (DRC) of Layout geometries in a VLSI layout. The algorithm assumes the parallel architecture to be a two-dimensional mesh of processors. The algorithm is based...
We will also look at the Design Rule Checks proposed by the foundries (for example: TSMC, Intel, Samsung, etc.) and explore how they are targeted for the specific technology node (e.g. 28nm,16nm, 7nm). The main objective of the Design Rule Check is to achieve reliability in the...
VLSI algorithmsDistributed ComputingCustom Design toolsIn this paper we provide a distributed solution to perform Design Rule Checking (DRC) of a layout by exploiting either spatial independence or layer independence in layout data. We show that the former approach to DRC can result in reasonable ...
Design rule checks(DRC) is the process of checking that the geometry in the GDS file follows the rules given by the foundry. Logical equivalence checks(LVC) is the process of equivalence check between pre and post design layout. Step 11. GDS II – Graphical Data Stream Information Interchange...
Design Rule violation is one of the major challenges being faced by VLSI industry. With ever shrinking technology nodes, and ever increasing gate counts, reaching to more than 40 million on a single die, the complexity of the design is momentous! Often, the so called “high priority goals”...
In a multi-wide class design layout, design rule checks for enclosure of multi wide class objects prevent false errors or false passes by performing such checks against the non-virtual boundaries of a wide class object, and not against the virtual boundaries. An exemplary embodiment provides a ...
1. A method for checking a set of layout design rules on a region of an integrated circuit layout, the layout including a plurality of shapes each having shape corners at respective locations in the layout, for use by a computer system having access to a design rule data set indicating con...
