What is the replacement of function "Reconnect" of OrCAD Layout in PCB Editor.

I want to connect two pins of footprint with Ratsnets connection in OrCAD PCB Editor. I used OrCAD Layout to design PCB. But there is much difference between two.
The function of the pin "Reconnect" in layout is to direct the connection line between two pins. We can then route that lines using routing option.
I try much to find that option in PCB Editor(That yellow line called "Ratsnets" in PCB Editor). But fails!!
Can anyone suggest me how to define connections between two pins in PCB Editor?

Connections are generally defind by netlist. You must creae schematic and forward annotate it to PCB.
You can also change net connectivity by selecting Net Logic from Logic Menu.
Changes are done in options pane (select net from dropdown and click on pins on main view to connect or disconnect nets).

Hi awaw, Thanks for reply. But I am talking about that function of OrCAD v9 in which you can just open PCB Layout application and by selecting the "Place" icon and right click --> select new(To place package) --> Place packages --> click on "Reconnect"(to assign connections to pins) --> connect pins whichever you want(Of course DRC error will be generated).
My question is -Can we do exactly that things in OrCAD v16.3?

I can generate netlist and create PCB. But for very small PCB's I would like to directly select packages and connect pins and create PCB rather than giong to the whole processes like creating schematics, assigning footprints and generate net lists.
All these things, I can do in OrCAD 9 and I strongly believes that these can be happened in new versions.

I have not more experience of OrCAD v16, so I would be grateful to you if you can help me. Thanks again.

I have no expirience in Orcad Layout and not sure that i fully understand this function.
But you can make new connections even from blank spaces and pins, not only pins with assigned nets. If you don't have a netlist then place package and simply route traces beginning from any point. You get traces with a netname "dummy" assigned, verify it with show element command.
Is this a solution?

Thanks for suggestion,
The function describes simple thing that u can create new connections to the pins.

By the way, I have done that try where i place the package and routed traces for connecting pins and the net named the "Dummy net". But after all, the trace is not bounded to the pins. When I moves the package then the package moves but trace resides where it is. Or we can say that, the trace is free from the package.
Another thing is that, when I place the package, it does not assigned RefDef or it names like "C* and R*". I think that OrCAD does not consider that packages as the component so that it cannot be routed. is it?

Ok, now i understood. PCB Editor is bad choice for such things. It works with netlist and is good for big projects and not for drawing from scratch. But you can, if you want.
First, go to preferences and verify that logic_edit_enable option is checked. Then go to Logic-Part Logic and create new component by selecting a package from library and setting minimum required feilds refdes and device. Before pressing "add" you must have a "device file" that maps component internals to package (text format, look for it in help or in previous projects). Then go to Logic-Net logic. Open options pane and press create. Create a new net. Select "assign" and pick some pins, then press done. You created a new net with connectivity and can route it. Change any other net with net logic command by deassigning and assigning pins again.
Look, all these tasks are very time consuming and comparable to drawing a usual schematic. :)
 

Re: What is the replacement of function "Reconnect" of OrCAD Layout in PCB Editor.

OK, I checked the option logic_edit_enable. But I am sorry to say that I can't find the option "Part Logic" and "Net logic" you described.
Are there options under "Logic" tab? You say that "setting minimum required feilds refdes and device" so how can I do this.

I understand that PCB Editor is the bad choice for this but I think this software have some great features that other can't.
So, Please help me to understand.
 

Re: What is the replacement of function "Reconnect" of OrCAD Layout in PCB Editor.

Yes, of course, these options are in Logic menu, not in preferences. If you don't see it try to change product via File-Change Editor... Maybe this helps...
 

Re: What is the replacement of function "Reconnect" of OrCAD Layout in PCB Editor.

Sorry for late.
I don't see any options like that.
Any way, I think that I should go for generating net lists and making board.

I found another program for that type of work, that is "Eagle". It is very nice, but I need to learn that.
Thanks for helping me.
Any other advice will be welcomed.
 

Re: What is the replacement of function "Reconnect" of OrCAD Layout in PCB Editor.

What version of PCB Editor you use? Can you show screenshot of an about window?

Eagle is not comparable with Allegro. But maybe it has exactly this feature.
But i think that netlist is better in any case. Normal schematic is very helpful and not so time consuming to skip them.
 

Re: What is the replacement of function "Reconnect" of OrCAD Layout in PCB Editor.

Hi, awaw.
First of all- I am sorry for a long time.
Hmm. I am using v16.
Well, you are right that the net-list is the better way to make PCB. We have to just make proper connections between the pins keeping in mind all of the PCB designing issues where we need not think about the connection problems and other physical problems in using the net-list method because all of that type of checks can be performed in software.

But if we want to make small PCB containing not more components where we don't have to think more about, then we can take the use of some small PCB designing softwares. And if we want to make more complicated boards, then go for the large programs like PCB editor.
I think we cannot directly make PCB in PCB Editor .Or if we can, then it must be going through bunch of steps to make connections. In that way we can use small programs to quickly make a board.

By the way, very much thanks for your support.
