The HExtract Plug In is used to extract a small window from a GDSII/OASIS file into a new GDSII or DXF file. The HExtract plug-in supports both flat and hierarchical output.

Once installed, you can access this function from the Tools drop down menu.

 




Usage

Turn on layers that you wish to extract. Data on a hidden layer will not be extracted.

Zoom in to the region you wish to extract. This need not be exact but in deep enough to see where you want to draw the extraction window.

  Extract Window selection



The HExtract Dialog

Open the Hierarchy Extract dialog by clicking on the Tools drop down menu and selecting Hierarchy Extractor. Then select either Extract to GDSII or Extract to DXF.

Now check the extract settings and define the window to extract.

Clip Data

 

if you want the complete entity that crosses the window edge then disable clipping. If you want any entity that crosses the window to be clipped at the edge then enable clipping.

 

Extract Text

 

if you want text entities exported check the Extract Text button.

 

Generate Flat Output

 

if you want to preserve cell hierarchy, disable the Generate Flat Output checkbox.

 

Extract Window

 

Define the window to extract. You can do this in three ways:

  • Click on Use Current View if you wish to extract the visible window.

  • Click on Draw Window and then click for first corner, release, and drag to second corner. Right click and End Rectangle to update your window.

  • Enter Coordinates Manually - Type in your window by specifying the LL and UR.

    entering coordinates manually
 

Output File Name

 

Use the Browse to define the output file name.

 

Extract

 

Once you have determined that all settings are correct, press the Extract button.




At right is the extraction window.

 



Results

At right is the extracted file. Because the cell G94S0F36 was completed contained within the extraction window, this cell (and all hierarchy below it) was not exploded. This can be very important if one needs to mantain as much hierarchy in the output file.
