First we need to export our cell layout to gds format. Since we will create abstract view and .lef file outside icfb, we need a global file format to transfer the information. This format is .gds file format. Abstract Generator will import the gds file of the cell library and then generate the abstract.
First we should go the the CIW window, click File->Export->Stream... A Stream Out window will pop up. In Run Directory, type in abgen/. In Library Name, type in the cell library name-SimpleSCL. In Output File, type in SimpleSCL.gds. The window is shown below:
Click on User-Defined Data, in Cell Name Map Table, type in stream.map.
Click OK and go back to the Stream Out window. Click Options. In Convert Pcells to Geometry, choose no merge.
Click OK and go back to stream out window and click OK
The exporting operation will begin and at the end there will be following message.
We can discard the warning message and go on to the next step.
