If something seems weird you have a net list you can read. Doing designs for clients using other CAD systems, where a Protel schematic is not available, the netlist method is the only method. But when one is making changes back and forth between the PCB and the schematic, the synchronizer is really cool. It's faster. Especially where there are a lot of new footprints and problems with pin numbering, etc., the difference can be significant. I have a old habit of simply changing footprints in PCB when there is a problem. It's a bad habit. Fixing the footprints from the schematic end prevents other problems down the line. I suppose if we are paid by the hour, re-inventing the wheel is a feature, not a bug. Don't be too shy to use the synchronizer. I recommend running a netlist *also* at the end of the design process and loading it, for security, to make sure that no macros are created -- or that one clearly understands what they are, in detail, if any *are* created. (Such as the multiple pad load bug, etc., or the lower case pad designator problem I described last night.) (I have not verified that the synchronizer has the same problem.) Reloading the net list is the only way to verify that one has not inadvertently edited a pad net assignment or deleted a component. DRC will not tell you. DRC should *always* compare the loaded net list with an external version. This simply change would increase the security of DRC. This would require that the synchroniser always generate a net list. I think it skips that now. It shouldn't. Net lists are at worst harmless and relatively small files. [EMAIL PROTECTED] Abdulrahman Lomax P.O.
