Re: [PEDA] FW: Access violation -- Is it a Protel bug?
I have tried to reproduce this behaviour by creating a schematic symbol which is associated with footprint BLANK. No ERC errors in the schematic. Generating a PCB using PCB WIZARD and using UPDATE PCB does not cause a problem. The updated PCB displays two of 6 components (not including the BLANK) the rest are not visible. FIT BOARD and FIT DOCUMENT causes a zoom to maximum size (10mil). With designators and comments hidden the two visible components can be selected and moved. With either designators or comments unhidden attempting to move either of the visible components causes a selection choice of the visible component and BLANK. Selecting in free space selects BLANK. Hiding Designators and comments, then using MOVE COMPONENT and SELECT COMPONENT with move component to cursor selected all components except BLANK were moved to within the PCB outline. FIT BOARD and FIT DOCUMENT now behave as normal. Looks like a BLANK creates a very large invisible footprint. Hope someone finds this useful. I can send the .ddb to anyone if interested.

For some reason, Protel does not like the footprint Blank(there is not primitive on the footprint at all). I deleted component note from the netlist, it seems ok now... Shuping Interesting - can this be validated (if someone validates I will add to the bug list). Proposed entry (if validated): Summary: PCB:Netlist load specifying a footprint with no primitives causes access violation. Details: PCB 99SE SP6 A netlist load which includes a footprint with no entities (a completely blank PCB footprint) can cause an access violation during netlist load. This does not affect the synchroniser. Workaround: Completely blank footprints should be avoided. Protel should make netlist import bullet-proof such that any file, even complete binary garbage, should not cause a crash. Reported by: Shuping Lew Validated by: I would especially like validation that this indeed the only way of triggering the issue or whether it requires other conditions as well such as large number of components, multiple instances of the blank component (maybe all with the same or possibly blank ref designators). Also, checking what the effects of the blank footprint on the board is (is it reported in BOM, does it affect Zoom-ALL). Maybe there is another bug in that a blank footprint causes the database to become unstable in some fashion. As per usual, I will do the database if others put in some time on the validation, thanks.

Re: [PEDA] FW: Access violation -- Is it a Protel bug?
Thanks Dave, One more thing, can you try creating a netlist and then try loading that into a PCB using the Netlist Manager | Netlist Load command (as opposed to using the Update PCB synchroniser). Does it crash? This would then confirm Shuping's bug and the proposed bug database entry. Probably, be a good idea not to have too many other important files open when you do this :-) Sounds like there are lots of reasons to avoid using footprints that are blank (that is have no entities).

Re: [PEDA] FW: Access violation -- Is it a Protel bug?
Ian, Creating netlist and Load Nets produces the same behaviour with no crashes. Perhaps having a small number of components makes the difference or maybe it's the size of the BLANK footprint.

Re: [PEDA] FW: Access violation -- Is it a Protel bug?
Regardless of ERCs or not, a netlist generated by Protel SHOULD NOT crash Protel. Period! I'd say if this 'crash' occurs on more than one machine, then it probably is a bug. If it only happens on his machine, it might be something goofy with his setup (bad bits on the hard disk, EXE tweek, etc) It should go to Protel for eval.

Re: [PEDA] FW: Access violation -- Is it a Protel bug?
Ian Wilson's questions are good ones. Did you enter the schematic and generate the Netlist? If you entered the schematic, and if it is an option, I would begin by resetting all Identifiers to ?. That is, do a global change of all R's to R?, all C's to C?, etc, for all components. Then use Tools/ Annotate to reannotate all ? components. Then generate a new Netlist and try loading that. Be sure to have all required PCB Libraries open for component footprints called for by the Netlist. Good luck! Brian At 04:14 PM 4/16/02 -0700, you wrote: Brian, I am using Protel 99SE sp6. The operation systems is Window 2000. I have over 500 mb of Ram. Tried to load a netlist to a new PCB document. There is no warning for the netlist report. I am not sure what I should do to solve the problem.
