Suppose you need to pull out only a tiny part of a very large chip design for a special analysis. How to do it? Use Qckvu’s Extract function. Below you see a chip layout with 21 layers and 500 structures. We really only need to pull out the metal/poly and vias from a small region. ![]() A 30 MB full chip design with 21 layers and 500 structures. (demo7.gds) First zoom in on region of interest and turn off all layers you don't want to extract. ![]() Now click on Extract. (Hmm, it seems the command name has been changed to Create GDSII ...) The Extract command is reached from the Tools | Create menu pick as shown below: ![]() You will be prompted to select a file name for the extracted data. In this example we selected the name: extract_example.gds. Then click on the SAVE button. ![]() Now using the mouse select a window on the display. (Click and drag keeping the mouse button down. When you release the second corner of the rectangle is defined.) Anything crossing the window gets pulled into a new, smaller GDSII file. ![]() |
ResultsIf we close the original file and open the newly created one, extract_example.gds we will find that Instead of 500 structures and 21 layers you have 1 structure and 5 layers. The original file exceeded 30 MB - the extracted file is 10 KBytes. It took 1 second to extract. ![]() One thing to notice - any entities that crossed our window are completely extracted -- even the portion that lies outside the window. It is possible to have the entities clipped at the selection window boundary. |
