The NETEX JOB File

The NETEX engine manager reads an ascii file called a job file which we will refer to as the NJB file. This file contains most of the information that NETEX-G needs in order to compute and write out the nets.

How the Job File is Organized

There are multiple sections within the job file. Each section provides a certain type of information needed by program. The sections are marked with a beginning and a end of section keyword. Click on a section header to jump to the page describing that section.

B_LAYERS         <-- layer stackup [required]
E_LAYERS

B_LAYER_INPUT    <-- directory/filename of Gerber 
E_LAYER_INPUT        for each layer [required]

B_COMP_INPUT     <-- directory/filename of Gerber 
E_COMP_INPUT          representing components [optional]

B_WIREMODELS     <-- wire models and parameters [optional]
E_WIREMODELS

B_DIEINFO        <-- die outline and thickness [optional]
E_DIEINFO

B_WIRES          <-- wires segregated by tiers [optional]
E_WIRES

B_DRILL          <-- directory/file of gerber files 
E_DRILL              representing drills  [required]

B_NETS           <-- net labels with coordinate 
E_NETS               and stackup position [optional]

B_NODES          <-- port/pin labels with coordinate 
E_NODES              and stackup position [optional]

B_COMP           <-- component name and insertion 
E_COMP               coordinate [optional]

B_EXPANSION      <-- expansion parameter for proximity 
E_EXPANSION          net computation [optional]

B_EXTRACT        <-- net extraction directives [optional]
E_EXTRACT

B_VIASIZE        <-- entities on via layer larger than this 
E_VIASIZE            value are ignored [optional]

Any lines within the job file that are not embedded in a valid section are ignored by the netex manager.
