Before we start the Abstract Generator, we need to set up our running environment. Go to our home directory and type in:
cd ~/
mkdir abstract
cd abstract
mkdir tech
mkdir run
cp ../standardcell/abgen/tech.dpux
tech
cp../standardcell/abgen/SimpleSCL.gds
.
We need to change a line in tech.dpux. Open this file and put our running path on the first line, as the following:
Save this file and go back to tcsh shell.
Type the following
cd ~/abstract/run/
abstract -tech ../tech&
Abstract Generator then starts. The following window appears:
Click File -> Technology... Specify the path as in the following:
Exit this window and in the main window click File -> Library...
Then click File -> Import -> Stream (GDSII)... And in the popup window, give the path where our SimpleSCL.gds is, and choose the option as the window shows:
Click OK, and you will see the nand2x1 on the right window.
