In the SPB16.01 release, you can now import/export database parameters from Allegro PCB Editor in the standard XML format using the File> Export/Import> Parameters menu option.
The export functionality creates the parameter file (with a .prm file extension). The parameter file contents can be the following options.
Once you've exported parameters from an exiting board file, they an be imported into a new board file using the Board Wizard
In addition, you can use th batch mode for techfiles to read and write database parameter files.
Command syntax:techfile -r|-w -p [-o <paramtype> -o <paramtype ...] [<paramfile >] [<in design>] [<out design> ]
The techfile executable can be used to read a parameter file into an existing board.Command syntax:techfile -r -p [<paramfile> <layout>] [new_layout]
The techfile executable can be used to export a parameter file from an existing board. Command syntax: techfile -w -p [-o <paramtype> -o <paramtype ...] [<layout><new_paramfile>]
So, how many PCB designers are taking advantage of importing/exporting XML database parameters to seed board files? While we stress that editing the XML files should be avoided, I'm curious if some adventurous individuals are doing something novel with exported XML files to inject special conditions.
I'd like to hear from you.
Your best option to resolve the question you asked is to contact our Customer Support team by filing a new Service Request through http://support.cadence.com/
I failed to import a parameter file to my new design.
the parameter file came from an existing board.
I can send the file to you . please help.
pcb editor asked me to "select file to view" after importing and I don't know what file it wants.
Can you clarify what you require? Are you looking for an XML editor?
I am looking for a definition file to see this XML file other than MS Word that can only display data.
