[question] tcl script in design compiler

[iamczx]

design compiler tcl

current_design top
set ALL_DESIGN [get_designs *]
foreach_in_collection a $ALL_DESIGN {
current_design $a
set_fix_multiple_port_nets -buffer_constants -all

echo "** set_fix_multiple_port_nets at design $a ***"

}

and the result is :Current design is 'mux21_15'.
** set_fix_multiple_port_nets at design _sel22 ***
Current design is 'mux21_16'.
** set_fix_multiple_port_nets at design _sel22 ***
Current design is 'mux21_17'.
** set_fix_multiple_port_nets at design _sel22 ***
Current design is 'mux21_18'.
** set_fix_multiple_port_nets at design _sel22 ***
Current design is 'mux21_19'.
** set_fix_multiple_port_nets at design _sel22 ***
Current design is 'mux21_20'.
** set_fix_multiple_port_nets at design _sel22 ***
Current design is 'mux21_21'.
** set_fix_multiple_port_nets at design _sel22 ***
current_design $top_design
Current design is 'top'.

I am puzzled .Why the display is _sel22 *** ? I expected it to be the subdesign's name.
thanks in advance

example of tcl scripting in design compiler

current_design top
set ALL_DESIGN [get_designs *]
foreach_in_collection a $ALL_DESIGN {
current_design $a
set_fix_multiple_port_nets -buffer_constants -all

echo "** set_fix_multiple_port_nets at design $a ***"

}

and the result is :Current design is 'mux21_15'.
** set_fix_multiple_port_nets at design _sel22 ***

Hello,

You get that because get_designs command returns a collection. You have to "convert" the result from that command to a list and then you can print it out. Hope this helps!

Good Luck

get_designs

dont worry , it is a display by Synopsys TCL compiler . it will allocate number to each design .
Make sure that log contain no errror.

foreach all_design

Thanks for your reply.
But ,how to convert the result to a list?
use list command?
Can you give a example?
I try many times ,but can't get correct result.

Use the object name for each element from the collection.

For your script try this one:
get_object_name [get_designs $a].

Cheers! ;-)

current_design, design compiler

you alse can use
get_attribute [get_design $a] full_name
