Ultra High Performance Layout Data Browser

Deep sub-micron/nano process technology requires a huge number of OPC patterns and dummy patterns for mask data preparation due to the improvement of printability in mask and wafer processes. As a result, data require terabyte sizes in disk space. Mature data-viewing tools are unable to handle such a huge data as it is too time consuming. Whereas HOTSCOPE is an ultra-high performance data browser that allows users to open and view terabyte-sized data within a short time and provides quick hotspot check and layout analysis capabilities.

Besides having powerful analysis capabilities, HOTSCOPE is armed with two unique features: HOTFINDER and Net Trace. HOTFINDER provides a quick interactive layout check with pattern-matching capability for both exact and fuzzy matches. By using HOTFINDER, users can quickly check patterns such as spacing, notch, or jogs for both specified area or full chip data. In pattern matching, users can provide the target pattern interactively by clicking on the mouse button to get the matching pattern on the fly.

Net Trace not only provides highlighting of equipotent patterns in GDS2 or OASIS but also supplies schematic generation. Without LVS, HOTSCOPE generates schematics by using rule only. HOTSCOPE recognizes devices, transistors, resistors, and capacitors and extracts SPICE netlist from the data pattern with layout parameters. By using these functions, users get efficient layout analysis for LSIs, including CMOS analog devices. Transistor-level Net Trace for DEF data is also possible by overlapping a GDS2/OASIS pattern on it. Additionally, remote accessing capability for design and mask data by multiple divisions and locations enables information sharing and increases communication among them.


  • Stress-free data handling for huge designs and mask data
  • High performance and automated check and analysis tool for layout data, including MOS analog block
  • Increased productivity due to data sharing and communications
