Qckvu3 Plug Ins

Qckvu3 supports a C++ plug-in architecture allowing users and third parties to develop custom applications on top of the layout viewer platform. The plug-in interface is available on Windows and Linux -- both 32 and 64 bit.

Available Plug-Ins

Plug-ins are listed below with links to pages that show their function in more detail.

Extract GDSII - This plug in enables a user to define a window and extracts everything crossing that window to a new GDSII file. The user can choose whether to have crossing entities clipped at the window edges.   Smart Die - This plug-in scans the pad openings of a die and finds the pad centers, pad sizes. It also numbers the pads (CW or CCW) and can associate test labeling the pads with the signal/net name. The output is an ASCII file in AIF format.
CSV Reader - This plug-in reads a CSV delimited ascii file and uses it to draw markers or contours on the display. It was designed to display items such as DRC errors or hot spots over a display of the layout.   Geometry Walker - This plug-in opens a GDSII layout and also a GDSII file representing XOR slivers. It then allows the user to jump from sliver to sliver and zoom it quickly and automatically ...
HExtract - This plug in enables a user to define a window or polygon and hierarchically extract everything crossing that window to a new GDSII file. NEW - we've added a circular clip window specifically for wafer trimming ...   Metal Density Calculator - This plug in enables a user window a region in a layout and then computes the metal "density" or "area fill" in that region. Supports a circular window for full wafers.
NetTrace - an on-the-fly net racing routine that works directly from the GDSII/OASIS layout and stackup information.   Target Bitmap Acquisition - user defines the camera field-of-view and resolution; then clicks on a target or alignment mark. The bitmap is extracted along with the bitmap's coordinates.
3D Export - This plug-in enables a user to define a small XY window and to define a layer stackup for a GDSII file. It then extracts all data inside the window, applies the height and thickness information and creates a 3D output.   Target Coordinate Acquisition - This plug-in enables a user to click on a target, automatically finds the center and exports the coordinate to a file.

File Merge Overlay - This plug-in enables a user to load (by merging) two GDSII files and to view them simultaneously. Very useful for comparison or for other analyses ...


Design Rule Checker - A plug-in that would run several different design rule checks on a layout. This would include spacing rule check, minimum line width check and enclosure check.


The Plug-in developer has a wide range of API's that access both the layout database and control the viewer.

Open and Close Files - The API allows a plug-in to open or close a layout file for viewing.   Select Structure and Layers to Display - The API easily enables a plug-in to control the structure/cell to view and to turn on/off layers.
Identify Objects by Vertex - The API enable the plug-in to select a point and then pull up info on any object near that point.   Extract Data - The API allows the user to extract data by point or by window. Supports hierarchy with DXF and GDSII output.
Pan and Zoom - The API enables the plug-in to pan and zoom the display.   Draw - The API enables the plug-in to draw basic entities on the screen.

CSV Reader - This plug-in was developed as an example to show how to write a plug-in and how to do some simple interaction with Qckvu3. The PDF includes code and comments and one can contact us to get the code separately.


Polygon Window Extract - this simple Windows plug in demonstrates how to draw a window on screen and use it to extract all the polygons crossing the window to a simple file.

Hello World - this simple Windows plug in demonstrates the minimum API's needed to interface with Qckvu3 and just does a hello world.

Sample Template - this simple Windows plug in template demonstrates how to create a basic dialog box that interacts with Qckvu3.

CSV Reader - this simple Windows plug in reads a CSV (comma separated field) and jumps from location to location based on the info in the CSV file. A marker is drawn at the center of the window and layers can be turned on/off.
