Netex-G Library Revision History
This page contains revision history for the NETEX-G library which is used by OEM partners who wish to tightly integrate NETEX-G functionality into their applications.
Version 1.17 4/13/2021Dropped data with respect to isolated vias.
This condition caused all nets but the one(s) containing non-connected vias to appear. This has now been fixed.Fixed interpretation of X multiplication in Gerber Macro
The 'x' multiplication operator was being supported but not the 'X'. This has now been fixed.Scaling large files over 2GB
Scaling would fail and report error when some of the intermediate files were over 2GB. This has now been fixed.
Version 1.16 3/18/2021Added a net information output file with GDSII export
When a GDSII output file is generated, a net information file is generated (base_name_netinfo.txtNetexG Windows Library ODB++ Scan
The bin folder contains odbscan_exec64.exe executable.
The bin folder contains odbscan_exec64.exe executable and a odbscan_exec script for setting up environment.
Version 1.15h 3/3/2021Software Updates
Boolean and Gerber validation components have been updated.
Version 1.15g 2/9/2021Software Updates
Boolean components were updated.
V1.15f Windows 1/28/2021Software Updates
Suppress output of component pin vias in ANF output. These vias (entries starting w/ V) are not needed since component pins (entries starting w/ X) are already provided.
V1.15e Windows 10/20/2020Software updates
Layer names in 3d output now appear as basenames of Gerber files created from OBB++ importing or from a user instead of the designations found in the 2nd column of B_LAYERS or B_AUX_PROPS sections of .njb file.
V1.15d Windows 9/16/2020Software Updates
This version includes an updated boolean engine and library which addresses several bugs involving crashes and dropped data.
V1.15c Windows 8/5/2020Fixed incorrect associations of node text to nets with wires
This occurred when multiple identical net labels on separate physical nets were employed. This caused the associations of nets to net numbers to be misaligned by the number of physically merged nets found in GDSII and DXF output. This has now been fixed.Misc updates
odbgui64.dll and odbgui_main64.dll are used instead of odb2gbr64.dll
V1.15b Windows 1/10/2020Fixed Padstack Generation
Padstack generation finds, for each via, the largest Gerber flash on each metal layer the via traverses. If the flash size is greater than the via size filter, smaller than the via drill size, or it's on a
scratch layer, the flash is ignored.
This version includes enhancements to boolean engine with respect to Gerber validation.
This new version supports ODB++ scanning features. The usage is illustrated in the sample program and ODB++ example batch file.
Revised STEP and PARASOLID argument check. If "-unionize or "-arc" argument is encountered with "-fea" option, a warning is displayed for their unsuitability to FEA.
Includes support for STEP and Parasolid outputs.
A number of new arguments that enable direct output of STEP and parasolids formats (using new libraries previously part of 3DVU's STEP and parasolid export) have been added. See the page Library for details.
v1.13 9/19/2017New version for Windows 64 and Linux 64
This version only supports 64 bit on Windows and Linux. 32 bit components were removed. It also includes support for MS VS 2015.
v1.12 5/25/2017ODB Import Layer Groups
The sNETEXGLIB_IMPORT struture has a new field, "omitGroups", which is an array of integers where each element is a flag for a layer group. The constants in the "eImportGroup" set are defined in "ntxg_lib_const.h". Currently, only soldermask, silkscreen, components, and rout, are recognized.
This was implemented for a user who wanted to import the copper stackup only without having to enumerate the copper stackup layers.
Added Incremental Extractions Capability
The "extractions" field of type sNETEXGLIB_EXTRACTIONS was added to the sNETEXGLIB_OPTIONS structure. It contains the following data fields:
DATA FIELD DESCRIPTION fileInput Name of file containing extraction requests keepIncrInfo Tells library to keep incremental files for subsequent runs. useIncrInfo Tells library to use incremental files for actual runs count Reserved for internal use list Reserved for internal use
The format of the extraction file is as follows:
<EXTRACTION_SET_1> <EXTRACTION_SET_2> ... <EXTRACTION_SET_N>
Where each set has the following format
B_EXTRACTIONS [BASE_NAME <name>] [<NET_NAMES>] [<WINDOW(S)>] E_EXTRACTIONS
The <name> after BASE_NAME is the name of the file to use to generate output filenames. In its absence, the main output filename is used to that end.
[<NET_NAMES>] is in the following form:
B_NET_NAMES <NM_0> <NM_1> ... <NM_N> E_NET_NAMES
Each <NM_M> is either a literal net name or a regular expression depicting one or more nets to be included. In the absence of this sub section, all nets are included.
[<WINDOW(S>] is in the following form:
<W_1> <W_2> ... <W_N>
Each <W_N> is either in the form of
CWH: <CENTER_X>, CENTER_Y> <WIDTH> <HEIGHT>
LLUR: <LOWER_LEFT_X> <LOWER_LEFT_Y> <UPPER_RIGHT_X> <UPPER_RIGHT_Y>
Extractions may specify net names and or windows. The net name extractions has yet to fully completed.
v1.11 4/25/2017New Argument to Library
The sNETEXGLIB_OPTIONS structure has a new field,"mgrArgs", which supports this. It is NULL by default, but if it points to a character buffer, whatever is in that buffer, is appended to the "netexgmgr" comand line.Update to Sample Program
The sameple program now has added "-mgrargs [arg(s)]" argument
The [arg(s)] are all the arguments that follow "-mgrargs". those arguments are collected and passed into the library's new "mgrArg" option field as one string. This string is then appended to the end of the "netexgmgr" comand line.
v1.10 4/5/2017Daisy chain licensing
The required output and import license(s) will be acquired and retained and will not be released until closing time.Rounded Thermal Draws
The ODB++ importer was revised with respect to rounded thermal draws.
The new behavior interprets the gap region in the same way as does Valor's Genesis which measures where the arc, computed from the average of outer and inner diameters, intersects with round ends. The previous behavior computed the gap as the space between round ends.
v1.09 10/11/2017Error and Warning File Formatting
Added missing newline characters to error and warning messages.
ODB++ Import Progress Display
pOptions -> preferences.advStgs.execDisplayMethodto one of two modes
NETEXGLIB_EXECDISPLAY_SINGLE or NETEXGLIB_EXECDISPLAY_MULTIPLE
the progress of ODB++ importing is displayed. The default mode is NETEXGLIB_EXECDISPLAY_MULTIPLE. To prevent displaying this progress, the mode to use is NETEXGLIB_EXECDISPLAY_NONE.
Licensing Library Update
The flexlm licensing library was updated to v126.96.36.199 from v11.3.
Revised Sample Code
v1.08 06/01/2016Initialize Error Return Structure
No details provided by programmer.
Added "-usestatwin" argument to the Example Program
This is a windows argument invoking the use of a built in Windowss dialog box rather than the use of the newly added status3f32 program.
v1.08 05/09/2016Added arguments to extraArgs sNETEXGLIB_OPTIONS Field
Error info structure return controls were added to this field:
-logerr2errinfo Excludes log errors + respective header and command lines in error info structure returns. -maxerr2errinfo:<val> Specify maximum <val> errors in error info structure returns. This is used in absence of -logerr2errinfo argument. Default is 100. -logwrg2errinfo Excludes log warnings + respective header and command lines in error info structure returns. -maxwrg2errinfo:<val> Specify maximum <val> warnings in error info structure returns. This is used in absence of -logwrg2errinfo argument. Default is 100. -add_errlog_hdrcmdln Adds respective header and command lines from log errors in error info structure returns.Fix Handling of Extract Section
The library was adding a duplicate of this section each time it was run. This has been fixed.
Error Log File Generation has been revised
The detail log token, <START_OF_NETEX-G>, is used to jump to the first program operation in the log file.
The detail log token, <END_OF_OPERATION>, is output upon encountering <END_OF_OPERATION> or <END_OF_PROGRAM_LOG> tokens
ODB++ Import Updated to support SIGNALLYR TYPE instead OF SIGNAL
No details provided by programmer
Added NetexGLib_GetFileName Function
