I want to display the Hspice simulation result without the UI of Avanwaves. And I turn to Meta Waves script. In script I wrote:

myvar = "writedriver.sp";
designOpen(myvar);
designFind(D0,"");
pnlAddCurve(1,node(D0,"tr0","v(vout)"),node(D0,"tr0","TIME"),0);
pnlShowPane(1,1)

The script was named "dispScript";
I ran the script in command line(cmd):

awaves -e dispScript

Then the problem turned out. Avanwaves ran, but it gave a warning message:"Cannot find node tr0:v(vout)"

OS: windows XP
Hspice version: HSPICE W2005.03

Could somebody help me with this problem. Many thanks.
