ISPD04 IBM Standard Cell Benchmarks with Pads
Contents
I. Introduction
This site contains the standard cell benchmarks used in the FastPlace paper published in ISPD 2004.
II. Benchmark Description
These benchmarks are derived from the ISPD-02 IBM-MS Mixed Size Placement Benchmarks
. The original benchmarks consist of macro blocks and hence had to be modified to be used for standard cell placement. The height of all the macro blocks was brought down to the standard cell height (16). The average width of all the modules in the original benchmark was computed and the width of all macros exceeding 4 times the average width was assigned to a value of 4X average width. All designs in the derived set have a whitespace of 10%. Also, these benchmarks have the connectivity information between the movable cells and the pads present on the placement boundary.
III. The Benchmarks
Note: If these benchmarks are going to be used in a publication or technical report, please cite [1] in addition to the URL. This paper describes how the benchmarks were created.
There are 18 benchmarks, ibm01-ibm18, available in Bookshelf format.
