I have been having problems generating a netlist for Allegro pcb editor from an OrCad schematic. I have created package symbols and padstacks for all of the parts I am using. In the Orcad schematic I have specified the allegro part symbols (.psm files) for the "PCB footprint" property. When I try to generate the netlist it fails because
#1 Error [ALG0012] Property "PCB Footprint" missing from instance C12: SCHEMATIC1, Buttons_Switches (8.30, 8.80).
There is a similar message corresponding to each schematic symbol. If anyone has experience creating an allegro netlist from an orcad schematic any help would be appreciated.
On another note I am able to manually place the packages I have created... I would be willing to skip the netlist step and manually enter the net information, but do not know how to assign a reference designator to a manually placed package symbol, and manually enter logical information. I do know that i need to set the logic_edit_enable environment variable... but using environment editor doesn't seem to have an effect on the pcb editor functionality...even though the logic_edit_enable variable is checked and after the saving the settings and reopening them it remains checked.
Sorry if these are stupid questions ... I am in college working the final stages of my senior project and have almost no PCB layout experience and am trying to pick up OrCad/Allegro very quickly. If can be of any help at all it would be greatly appreciated
Very strange. It works fine.Which version of orcad capture are you using? Works well with 9.2.3 , 10.x and 15.7 (dont know about previous version)Do you have CIS feature?When you double-clic on symbol, a window opens with properties.If you filter by "cadence-allegro", do you still view the right value in "pcb footprint" field?How do you extract netlist?Procedure:select dsn, tools->create netlistUse "pcb editor" (15.7 verson, maybe allegro in previous version, cant remind) page, check "create netlist" and "OKIt would create 3 .dat files in allegro folder wich can be imported in allegro.Maybe, check netlist.log file.Hope can help...
Check your psmpath.
... and padpath
Are you including the extension (.psm or .dra) in the footprint name. Allegro will not recognize the footprint if you do this. Also, if you have a leading space in the footprint field your netlist will generate errors. As asked above, what version of Allegro and Capture are you using?Regards,Harold Pattie
