Various problems importing complex pcb #102

Open albmac opened 3 years ago

albmac commented 3 years ago

Hi, I had some problems importing a pcb from Altium (17.0.6.354, not sure but at least 3 years old) . It's a 15 layer design with ~330 SMD footprints (a 200mm diameter circle). The converted .kicad_pcb file results in a number of errors, which I corrected in a text editor until Kicad pcbnew (5.1.8) could load the file; for each I copy the relevant lines: -message: 15 is not a valid layer count in input/source ... (11 In11.Cu signal) (12 In12.Cu signal) (13 In13.Cu signal)

(31 B.Cu signal)
...

Solved by manually adding layer 14 in the blank line above:
(14 In14.Cu signal)

-message: Expecting ")" in input/source (zone (layer ) (tstamp 547BA6E6) (hatch edge 0.508) Substituted with (layer 14.Cu) 279 times

-message: Expecting ")" in input/source (zone (net 414 "SDA_MUX1") (layer F.Cu) (tstamp 547BA6E6) (hatch edge 0.508) Substituted similar lines with (14K times): (zone (net 414) (net_name SDA_MUX1) (layer F.Cu) (tstamp 547BA6E6) (hatch edge 0.508)

-message: Expecting ")" in input/source (zone (net 941) (net_name VCC uC) (layer B.Cu) (tstamp 547BA6E6) (hatch edge 0.508) net_name is split in two words, substituted with single word like VCC_uC (13 times)

-warning: there is a zone that belongs to a not existing net "VCC_uC" ... and other nets Just ignored

-In the resulting design, zones have vertices all over the drawing space, up to 1.5m from origin, plus at least a vertex at [0,0] I deleted all zones

Could you provide the .PcbDoc for analyzing the odd layer number issue? If we count Front and Back layer too, I am counting 16 layers in your design. Due to the missing layer, the layer-references are broken. I have added some code to remove spaces from net names, I hope this will not cause collissions for someone else. I am currently working on the zones problem. Could you perhaps try to provide a minimum test-file that shows the errorneous zones with vertex at [0,0] ? The problem only seems to happen with huge files for me.

Sorry but the .PcbDoc is confidential (and quite big), I cannot share it. 16 layers counting the one I renamed (In14.Cu) but there seems to be nothing attached to it; the comments describe only 15 layers. Maybe the fastest solution would be an option to ignore fill zones (they are anyways likely to be removed and re-generated automatically in kicad). I don't have Altium so I unfortunately cannot provide test files.

Ok, no problem. I'll let you know when the bugs are fixed.
