Otherwise, to compare everything, select Compare Entire Layer.Ħ. If you only wish to compare a certain area of the layers, select the Window Area To Compare option. (For example, choosing 0.5 mils instead of 1.0 mils takes the system 4 times longer to process the data.)ĥ. The smaller the value, the more accurate the data must be to pass the comparison "test", and the longer it will take for the system to compare the layers. Accuracy is the tolerance to which each pixel can deviate between the two layers. Note that any differences found will be flagged on Layer 1.Ĥ. Select the two layers you wish to compare from the Layer 1 and Layer 2 drop-down lists. You can also open the Control Panel by using the Info > Find > Layer Compare Errors command, which is only available if you have acid traps flagged in your design.ģ. Note: If you have already run the layer comparison process, and simply want to open the Control Panel to view the flagged differences and make modifications, you do not need to go through the process again. Open or Import the design whose layers you wish to compare.Ģ.
To have as much memory available as possible, close other applications prior to using this feature.ġ. The more free RAM memory you have on your computer, the faster it will run.
Warning: This function is memory-intensive. Individual layers of a composite can also be compared. Essentially, it is like plotting both layers on film, then placing one on top of the other and seeing if they match. M.This command allows you to compare two separate Gerber layers and detect any differences between the two. pdf files showing the interpreted results of my Gerber files were excellent, very clear, detailed, as good as any check plots I've ever seen." -S. See what our customers have to say about our free design for manufacturability tool: "DFM worked great! The files were interpreted correctly on the first try, it even caught my silkscreen error. Get your free graphical PCB board file check report in minutes. This tool can potentially save you money because we can help you determine if your Gerber Files are ready for manufacturing. Click Here to link to a 3rd-party Gerber Viewer vendor.Īs you get closer to placing your PCB order, we highly recommend that you check out our FreeDFM tool. You will find that files output in 274-x format will import into most of these packages with no additional configuration needed. It's wise to use a third-party review to check your design. There are sometimes wide variations between what the design software shows and the output in the Gerber files. Don't assume that what you see in your design software is what the manufacturer will see. We strongly recommend the use of a stand alone Gerber viewer. Try the online Gerber file viewer linked on this page. We recommend a third -party review of your PCB design files.
