is it my gerber output from allegro true?

Hi
I am new in allegro and it is my first gerber output, it is really simply board but I don't know how I can create properly output?
so I attached my works if is it possible help me. and also suggest me simple and right application guide for creating gerber output.

Sincerely yours,
Siyavash.

You can use a gerber viewer and check the files yourself. e.g Graphicode GCPrevue which has a free version.. A quick check for your board shows that you have some unconnected nets, I can see that you have connect lines though, so you can use tools -> derive connectivity to connect the lines to the pins.

hi Hisham,
thank you for your helpful answer, but I don't know which work I should do that I understand my file is correct.
I understood for creating a gerber file from my PCB I should create these parts, but is there any complete application note that I can use it?
1.each layer
2.solder mask layer top and bottom
3.Solder Paste Layer top and bottom
4.Silk Screen Layer top and bottom
5.Fabrication Drawing Page 1(for Ref. ONLY)
6.Fabrication Drawing Page 2)for Ref. ONLY)
7.Assembly Drawing Page 1 (for Ref. ONLY)
8.Assembly Drawing Page 2 (for Ref. ONLY)
9.Drill tape, Layer 1 through 2
10.Drill tape, Layer 1 through 3
11.Drill tape, through
12.Drill tape setup file
13.Drill tape composite file (for Reference ONLY)
14.IPC-D-356 netlist (for Checking ONLY)
15.Artwork Format File (for Ref. ONLY)
16.Placement file for Assembly (for Ref. Only)
17.Allegro Netlist (for Ref. Only)

any help would be greatly appreciated,

If you want to know what does each part of the Gerbers do, then check this **broken link removed** it has a summary about each part of the PCB gerbers. (copper layer, solder mask, solder paste ...)

If that is not what you want then try to rephrase and I will help you. Furthermore ask your pcb house if they use ODB++ it will be easier, you will need to download the add on and export the odb++ file..

For double sided PCB, you don't need more than:

top and bottom signal
top and bottom soldermask
outline (missing from your posted files and lists)
plated nc drill
optionally non-plated nc drill

When using RS274X (as in your posted files), no format or aperture info is needed, just the mapping of file names and mm or inch info

Don't forget solder paste, best done at same time as rest of the Gerbers...

This tutorial shows the steps required to generate gerber in Allegro.

If you follow this you should be good to go.
