Now, open a new window on your workstation (or go to a different machine entirely) and start up the demo client called tcldemo. On the command line you must supply the IP address and the listening port where your Qckvu is running.

You'll see that the demo sends the command (only after you hit ENTER) to open the GDSII file called demo.gds. (When running the demo we assume that you have demo.gds in the same directory as the Qckvu. Otherwise you would have to send a full path with the file name.) Upon receiving this command, Qckvu scans and loads the GDSII stream file, but does not do any display calculations.

The next command is the "redraw" command. This forces Qckvu to draw the screen when you hit Enter.

When Qckvu receives the "redraw" command it proceeds to draw the screen. You will see the entire chip and all layers (this is the default when Qckvu starts up and we didn't issue any commands previous to the redraw to turn off layers...)
