Error (orcap_32042)

[PIERGIUSEPPE90]

Salve, stavo cercando di creare la netlist per fare il layout della board tramite allegro. Ho fatto il circuito, l ho simulato e ho fatto il design rules check ed è tutto ok, ma quando vado a creare la netlist mi esce:
Error (orcap_32042):netlist failed.Please refer to session log or netlist log for details.

Ma non capisco a cosa sono dovuti questi problemi. Spero che qualcuno mi possa aiutare. Grazie mille in anticipo.

Hai un duplicate packaging error -> hai chiamato due componenti con lo stesso nome.
Prima di compilare la Netlist devi fare Annotate, mi sembra si trovi sotto il menu Tools, se non ricordo male.

Ciao,
Pietro.

Ho fatto l'annotate:

ERROR(ORCAP-1377): Component U3A has different common pin connection for two instances and hence packaged separately.

INFO(ORCAP-1378): LAST USED REFERENCES

Non trovo niente che abbia lo stesso nome, né il problema relativo al componente U3A.

[PIERGIUSEPPE90]

Ce l ho fatta. Non mi da nessun errore e ho creato la netlist. Il problema era che non non avevo messo il net alias in un filo collegato a massa e ora il problema non c'è più. Non capisco cosa c'entra quell'errore che mi dava. Comunque io metto sto filo a massa ma non so il perché, ho fatto un full adder, e all'inerno di ognuno dei due half adder ho messo un ground e un pezzettino di filo col net alias GND ma non so a cosa serve. Il professore ce lo fece mettere nel primo progetto senza mai spiegarci a cosa serva. Potresti chiarirmi le idee? Grazie

[PietroBaima]

AH, ho capito.
Il simulatore richiede che ci sia sempre un nodo chiamato GND.
Ha bisogno di sapere chi sia il suo riferimento interno da porre a 0V.

Ciao,
Pietro.

PS_OT: sto cominciando a sviluppare un certo odio verso i professori faciloni (ma non è colpa solo tua, sono diversi thread a cui partecipo ultimamente in cui si parla di professori... un po' strani!)
