merging nets

Hello masamasa , You can use Logic > Net Logic to create or assing new nets. I have also written a sample code few days back, see if this helps you:

axlCmdRegister("merge_net" '_RBG_change_shape_net ) defun( _RBG_change_shape_net () let( list(old_netname new_netname l_shapes shape_count)
old_netname = "LED1" ;name of net to remove
new_netname = "0" ;name of combined nets
obj_count = 0
axlClearSelSet()
axlSetFindFilter(?enabled '(noall "shapes" "vias" "pins") ?onButtons
'("shapes" "vias" "pins"))
axlAddSelectAll()
l_obj = axlGetSelSet()
axlClearSelSet()
foreach(obj l_obj
if(obj->parent->net->name == old_netname then axlChangeNet(obj new_netname) obj_count++ );this if will work for shapes and vias
if(obj->net->name == old_netname then axlChangeNet(obj new_netname) obj_count++ );this if will work for pins
);end foreach
if(obj_count>0 then
printf("%n objects changed from %s to %s.\n" obj_count old_netname
new_netname)
else
printf("No obj found connected to net %s\n"
old_netname)
);endif
);end let
);end defun

; you need to change the old_netname and new_netname based on your design.

Hi Masa,

When creating the new netlist un check the option " Allow etch removal during eco"

Best Regards.

May be placing a zero ohm resistor in between can help

thank u very much.

it works perfectly.

i did not know that the net name is case sensitive, though.

regards
