Hi all, I have some questions about pcb.
1. I have the concept down of how pcb interacts with the components you place on the board and the netlist you load and I have them working properly, as I can properly highlight nets and components with the netlist browser. However, from what I can tell, there still isn't any concept of lvs in pcb, or am I missing that? Of course you can manually highlight and check every net as a manual type of lvs, but is there no automatic tool for this? If not, is there at least a way to make sure that your netlist and pcb have exactly the same number of components with the proper refdes indicated in your netlist (as in, there are no missing components, duplicate components, or misnamed components)? 2. I looked at the way pcb instantiates a component into the drawing area and it looks like instead of just referencing the footprint (as gschem does with symbols), it actually just copies the contents of the footprint file to the pcb, so if you edit the footprint it doesn't get updated. I can see why some might like this, as editing a footprint doesn't break the layout, but is there an option to just reference the footprint instead for people who want this? For example, if I have 100 footprints of 0805's and I want to change the mask clearance for all of these footprints it would seem as if I would have to do this one by one. 3. Right now, I am running gnetlist -g PCB on my schematics to generate the pcb netlist file. The problem is I have multiple schematics that I am generating a netlist from and I am manually appending the refdes to indicate which schematic the netlist comes from so all my refdes will be unqiue. (for example, instead of U1, it will be U1.A1). Has anybody developed some kind of script or flow to solve this problem? I would like to get away from doing this manually eventually. 4. Why doesn't pcb play nice with pins that aren't numerical? For example, if I have a netlist that references U1-vcc, and a pin named as U1-vcc, pcb will complain and won't highlight the pin/net. What property of the symbol in gschem is gnetlist using to determine what the pin number is? _______________________________________________ geda-user mailing list geda-user@moria.seul.org http://www.seul.org/cgi-bin/mailman/listinfo/geda-user
