i'm a newbie and i have two problems.. I'm trying to use PCB editor after designing a schematic. As a test, i used simple resistors from analogg library. When i create the DRC, this error appears:
#1 Error [ALG0081] Illegal character "Forward Slash(/)" found in "PCB Footprint" property for component instance R1: SCHEMATIC1, PAGE1 (2.70, 0.70) .
The 2nd problem appears when i use a transistor for example of PWRMOS library, that should have the layout model...But when a try to place it in the allegro pcb tool, nothing appears...I can select it from the menu PLACE-->MANUALLY but i don't seeanything.
Thank you to who can help me!
1st Problem - PCB Editor does not allow/like the use of special characters.../ , . \....or spaces. Remove those and for spaces I use the "_" which is allowed. See if that helps.
2nd problem - look at the command line on the bottom and see if it has an error message. My guess is it may be a problem with illegal characters as above or unable to find padstack....Does it say anything there?

Hi KEN13, thank you fot the herlp!
1) how/where can i change these characters?
2) i select a component from PLACE-->MANUALLY (but no footprint preview appears). After when I try to place it, atthe bottom appears the sentence "no element found"
In reply to fighter84:
1st problem...If you are using Capture for the schematic...Since you said this is a test...Open the schematic(suggest you save a copy somewhere just in case). Single click on the .dsn to select the design. Now on the toolbar select Edit...Browse...Parts. Highlight all the parts by holding the LMB and dragging. Once all the parts are highlighted Presss CTRL E to open the Editor window. Maximize the window and find the PCB Footprint field. Remove or replaced any illegal character. Select OK and save your design. Now try your DRC check. Note: The proper way to do this is to update the library footprints first and then use the replace cache option. You can do that later if you want. You will have to change the PCB Editor footprint name to match.
2nd problem. Not sure about the no element found...Check you paths to your libraries...Setup/User Preferences...under the Categories expand the Paths folder and select Library. On the right verify the padpath and psmpath have the library where the footprints are located listed. If not add them and see if that works.
I changed footprint field: from AX/RC05 to AX_RC05. I don't know if it's correct but now i can create the netlist Now i have the same problem pf powermosfets: I can't place them manually. I can select components from placement list, but i can't see a preview. When i try to place it, in the bottom appears "No element found". I don't know if I do some mistake.. For power mosfet I tried like you said(setup->user prefences, etc), but i'm not very sure about the library path, actually i copied and past :"Cadence->SPB_163->tools->capture->library->pspice" in which the orcad library PWRMOS is present.
Now i have some doubt about the presence of these footprints: forpowermosfet when i chose an istance in ccapture i see an icon red and gree and if i move the mouse near the text "layout" appears, so i thought i have the pcb footprint. The same for resistances (analog library)
Tahnk you for the patience
