Building the Command Line

Once the Job File is completed it is time to build a command line. When calling Netex-G from an external program one actually uses the program called netexmgr.exe (the netext manager) since Netex-G is actually a collection of modules and data and command lines are passed from module to module.

The command line is shown below. Breaks are inserted only for clarity and to allow annotation.

"C:\WCAD\NETEX-G\netexgmgr.exe"                 full path to the executable netexmgr.exe

"E:\cad_data\netexg_ex\pbga1\pbga1.njb"         full path to the job file

"E:\cad_data\netexg_ex\pbga1\output\pbga1.gds"  full path to the output file

"-wdir:E:\cad_data\netexg_ex\pbga1\working"     defines the working directory 
                                                for temp and log files.

-maxpts:1000                                    max num of vertices per boundary

-arcres:12.000000                               the arc resolution 

-arcsag:0.000000                                the chord error (arcsag is an older
                                                term for chord error 

-smoothing:0.020000                             the smoothing value (distance between
                                                adjacent vertices.

-outtype:gds_stream                             output to be GDSII

-cutlines                                       use cutlines for polygon islands

-textheight:1.000000                            text height for nodes = 1

Redirecting the Progress and Log Data

When calling the netexgmgr program it is useful to also redirect the output of the program to a file that one can use for information or can discard. Rather than have this data appear on the standard output we usually redirect it as follows:

command line > log >2%1
