—In this paper we propose a quantitative approach to analyze the impact of heterogeneous blocks (H-blocks) on the FPGA placement quality. The basic idea is to construct synthetic heterogeneous placement benchmarks with known optimal wire-length to facilitate the quantitative analysis. To the best of our knowledge, this is the first work that enables the(More)
Due to the continuous scaling of integration density and the increasing diversity of customized designs, there are increasing demands on the scalability and the customization of EDA tools and flows. Commercial EDA tools usually provide an interface of TCL scripting to extract and modify the design information for a flexible design flow. However, we observe(More)
X-ray computed tomography is an important technique for clinical diagnose and nondestructive testing. In many applications a number of image processing steps are needed before the image information becomes useful. Image segmentation is one of such processing steps and has important applications. The conventional flow is to first reconstruct the image and(More)
