Extract all symbols/nets from a design

serpens

Hi, I'm new with SKILL, I try to do some code and it works, but as I trying to go deeper I found some issues. I start to work with the database and as a exercise I want to extract all reference designators (or net names) from a board.

However, I was looking trough Allegro® User Guide: SKILL Reference but can not find nothing. I don't want from you to give me the code, I just need some advice in some methodology how to extract such things from database.

I found only this axlExtractMap (there is an example how to extract all net names) but if I understand it correctly it use already existing report files and I looking fore something without external files.\

Regards,

Miro

  • In the Allegro Skill Reference Manual see section 2 (Allegrp PCB Editor Database User Model). You want to look at the Design Attribute table. The symbol attribute reports the list of placed symbols while the component attribute reports all components whether its symbol is placed or not. Components match all of the parts referenced in the netlist and sport a REFDES.  If you place addtitional symbols (such as mechanical or format) that are not netlist they will show up on the symbol attribute but not in the component attribute.
