Importing and Exporting Data > ODB++ Exporter IssuesThe following known issues have been found regarding translated ODB++ directories. The problems occur when the contents of an ODB++ file do not completely conform to the Valor ODB++ specifications. The ANSYS ODB++ Translator response varies depending on the nature of the problem, and an informative warning/error message is provided.
Extra text after the part-name of a CMP record in a components file The one-word component part-name should be the final text before the terminating semi-colon in a CMP record (“;”). Any extra text is ignored.
Example with the extra text in bold: CMP 8 0.94074 0.3248 270.0 N J1 mPCIE EDEGE CONN ;0=1,1=0.000010
Duplicate pin numbers in TOP records in a components file Each toeprint record (TOP) for a component should have a distinct pin number. When a duplicate is found, the duplicate pin number is changed to an unused number. The user is given a warning.
Example: The bold pin numbers are duplicates. ...

A NET record in an eda data file contains extra text The net name specified in the NET line of an eda data file should not contain spaces. If spaces are present, they are replaced with underscores. A warning is issued. This situation could happen when net names with spaces are exported without removing the spaces.
Example: These NET lines from an edata/data file result in nets named JTG_ENA_TOP and JTG_ENA_PHY. #NET 973 NET JTG_ENA TOP ... #NET 974 NET JTG_ENA PHY
Duplicate pin names Duplicate pin names within the same component — as defined by a PKG record in an eda data file. When a pin name is duplicated, the translator forces it to be unique by appending a number. A warning is issued.
Example with pin names 11 through 18 used twice in the PKG record: # PKG 2 PKG smnhda18.2_39_ni 0.03937 -0.4084999 -0.24 0.3825 0.24 RC -0.251 -0.24 0.502 0.48 PIN 1 S 0.15745 -0.1284499 0 U U RC 0.14545 -0.1634499 0.024 0.07 PIN 2 S 0.15745 0.12845 0 U U RC 0.14545 0.09345 0.024 0.07 PIN 3 S 0.11808 -0.1284499 0 U U RC 0.10608 -0.1634499 0.024 0.07 PIN 4 S 0.11808 0.12845 0 U U RC 0.10608 0.09345 0.024 0.07 PIN 5 S 0.07871 -0.1284499 0 U U RC 0.06671 -0.1634499 0.024 0.07 PIN 6 S 0.07871 0.12845 0 U U RC 0.06671 0.09345 0.024 0.07 PIN 7 S 0.03934 -0.1284499 0 U U RC 0.02734 -0.1634499 0.024 0.07 PIN 8 S 0.03934 0.12845 0 U U RC 0.02734 0.09345 0.024 0.07 PIN 9 S -0.0000299 -0.1284499 0 U U RC -0.0120299 -0.1634499 0.024 0.07 PIN 10 S -0.0000299 0.12845 0 U U RC -0.0120299 0.09345 0.024 0.07 PIN 11 S -0.0393999 -0.1284499 0 U U RC -0.0513999 -0.1634499 0.024 0.07 PIN 12 S -0.0393999 0.12845 0 U U RC -0.0513999 0.09345 0.024 0.07 PIN 13 S -0.0787699 -0.1284499 0 U U RC -0.0907699 -0.1634499 0.024 0.07 PIN 14 S -0.0787699 0.12845 0 U U RC -0.0907699 0.09345 0.024 0.07 PIN 15 S -0.1181399 -0.1284499 0 U U RC -0.1301399 -0.1634499 0.024 0.07 PIN 16 S -0.1181399 0.12845 0 U U RC -0.1301399 0.09345 0.024 0.07 PIN 17 S -0.1575099 -0.1284499 0 U U RC -0.1695099 -0.1634499 0.024 0.07 PIN 18 S -0.1575099 0.12845 0 U U RC -0.1695099 0.09345 0.024 0.07 PIN G1 T -0.3959999 0 0 U U CR -0.3959999 0 0.0125 PIN G2 T 0.37 0 0 U U CR 0.37 0 0.0125 PIN 11 S -0.0393999 -0.1284499 0 U U RC -0.0513999 -0.1634499 0.024 0.07 PIN 12 S -0.0393999 0.12845 0 U U RC -0.0513999 0.09345 0.024 0.07 PIN 13 S -0.0787699 -0.1284499 0 U U RC -0.0907699 -0.1634499 0.024 0.07 PIN 14 S -0.0787699 0.12845 0 U U RC -0.0907699 0.09345 0.024 0.07 PIN 15 S -0.1181399 -0.1284499 0 U U RC -0.1301399 -0.1634499 0.024 0.07 PIN 16 S -0.1181399 0.12845 0 U U RC -0.1301399 0.09345 0.024 0.07 PIN 17 S -0.1575099 -0.1284499 0 U U RC -0.1695099 -0.1634499 0.024 0.07 PIN 18 S -0.1575099 0.12845 0 U U RC -0.1695099 0.09345 0.024 0.07
Property line contains multiple words for property name A property line (PRP) should contain a single-word property-name followed by a quoted string for the value. Some PRP lines have multiple words that precede the quoted value. In this case, it is assumed that the extra words are intended to be part of the property name and they are then concatenated together with underscores. A warning is issued.
Example: PRP SIMULATION MODEL 'MAX2003'
Property line contains extra text after value A property line (PRP) should contain a single-word property-name followed by a quoted string for the value. Some PRP lines have multiple-quoted values. The text after the first quoted value is ignored. A warning is issued.
Example: PRP PART LABEL 'RELE' TN2C'
Property line is missing value A property line (PRP) should contain a single-word property-name followed by a quoted string for the value. Some PRP lines are missing the quoted value. When this occurs, the property is ignored. A warning is issued.
Example: PRP Manufacturer
Discrepancy between component file and eda file A correlation exists between the toeprints specified in the component file and those specified in the eda file. If the files are created incorrectly and their indexes do not match, the ODB++ Translator aborts translating the components file. Overall translation is continued, but components, padstacks, and nets are not translated. A warning is issued.
Negative net index specified in components file Toeprints in a component file should have a positive net index. If the net index is negative, the ODB++ Translator aborts translating the components file. Overall translation is continued with padstacks and nets being translated, but components are not translated. A warning is issued.
Example with net index in bold: TOP 1 6.31 7.9018001 0.0 N -1 0 2_3
The eda data file contains a trace subnet with a hole feature Trace subnets (part of eda data file) should have only copper features as members. If holes are found as trace members, the hole feature is ignored. A warning is issued.
Example with hole feature in bold. SNT TRC FID H 6 4717
Features from multiple padstacks are listed in the same toeprint in the eda data file The features listed for a toeprint in an eda data file are to be from the same padstack. When features from multiple padstacks are found in one toeprint warnings are issued. The first padstack is translated normally. Pads and hole from the other padstacks are merged into the first when possible.
Arc definition is incorrect Arcs are specified in ODB++ directories with a start point, end point, and center point. The distance from the start point to the center should be the same as the distance from the end point to the center. If the two distances are different, an arc can not be created, and instead, the start and end points are used to create a segment (0 height arc). A warning message is issued.
Holes not specified in eda data file Padstack via and pin holes are specified in the eda data file of the ODB++ directories. Following is an excerpt of an eda via specification. FID entries specify each part of a via: holes, pads, and antipads. Entries containing "C" are pads (copper), and entries containing "L" are antipads (laminate). Lines containing "H" specify holes, but there are no holes specified in this example because a known problem exists wherein hole features are not specified in the eda data file.
SNT VIA FID C 2 8479 FID C 3 10992 FID L 4 1310 FID L 5 2414 FID L 8 1310 FID L 11 1310 FID L 14 2053 FID L 15 1310 FID C 16 5566 FID C 17 3399
If "H" lines were present they would be indicating which feature from which layer is to be used for the hole. Hole features are found on ODB drill layers. There is a drill layer defined in this ODB directory and it does have features. But because of a known problem, holes are not specified in the eda data file, so “H” lines are not present in the file.
A line in the feature file contains a non-numeric attribute value The feature file contains lines that list numeric values which specify the setting of various attributes and options. The following feature line mistakenly contains an attribute with a string value instead of a numeric value.
P 3.6765000 2.4700000 0 P 0 0;0=0,1=NO,2=1
The attribute will not be used and a warning message is issued.
Non-numeric value for attribute on feature line in the features file Feature lines may have attributes specified at the end of the line. The value for an attribute is omitted for boolean attributes. Otherwise it is an number representing either the numerical value for integer and float attributes, an option number for option attributes, or an integer referencing a string from the attribute text string section of the file. The feature line below has a value that is a string, rather than either being omitted or a number as is correct.
P 3.6765000 2.4700000 0 P 0 0;0=0,1=NO,2=1
The attribute will not be used and a warning message is issued.
Missing package name The PKG record in the eda data file is missing the required package name. There should be a package name in the underlined space below.
# PKG 0 PKG 0.1 -0.1275 -0.0275 0.9275 1.0275
Package contour hole before island in eda data file A package contour specification for a footprint outline mistakenly specifies a hole (H) before it specifies the island (I) that could contain it. The hole is ignored and a warning is issued.
# PKG 20 PKG T 0.03937 -0.2411574 -0.0492126 0.1688426 0.146504 CT OB 0.0327165 0.040748 H OS -0.068451 0.040748 OS -0.068451 0.040441 OS 0.0327165 0.040441 OS 0.0327165 0.040748 OE OB -0.068451 0.0856299 I OS 0.0327165 0.0856299 OS 0.0327165 0.1415828 ...
Features on negative layers specified to be copper rather than laminate Subnet toeprint features in the eda data file that are on negative layers should be specified as laminate. Some tools incorrectly export them as copper. When this deviation is supported, the feature is used as if it is laminate; the feature becomes an antipad. Copper features in a subnet toeprint are pads. In the FID line below layer 5 is a negative ODB++ layer, the "C" should be an "L". SNT TOP B 32 0 FID C 5 598
