A Tcl beginer's problem

Hi
I got a problem when leaning the tcl for synopsys tools.Why the follow
command line is wrong.

foreach my_port [filter [find port *] "@port_dirction == in"] \
{ set_drive -rise 0.1 $my_port \
set_dirve -fall 0.1 $my_port \
}

Thanks
 

Re: A Tcl beginer's problem

Hi, you can set your input ports like this:
set my_port [remove_from_collection \
[get_ports -filter {@port_direction == in} "*"] \
[concat $clk_ports $rst_ports $test_ports]];
set_drive -rise 0.1 $my_port;
set_dirve -fall 0.1 $my_port;
But i don't know why you set drive of your input ports.
We just need set this for clock networks.

hi,horzonbluz
Thanks for your help!
Im a beginer of DC. I think My mistake is that the command "set_drive" can accept a port_list input, and the "foreach" command is unnecessry.
Could you give me another help? Which site can i find some useful script of dc for practice?
Thanks!

TCL - Tool Command Language. Many ASIC Design tools have TCL interface:

DC-Shell, NCSIM, MTI etc.
A good TCL Tutor is available on the web that I use. Sorry, don't have the link handy, a simple google search for "TCL Tutor" should provide the link.
