Priorities
Its possible that association information could be provided from multiple sources in
which case the possibility of conflict arises. If this is the case the following priorities
apply:
1.
User supplied association (e.g. using the associate symbols and models dialog)
takes precedence over embedded association
2.
Embedded association takes precedence over pre-defined association. Predefined association is what is stored in the ALL.CAT catalog file supplied with
SIMetrix
Catalog Files
The data for model and symbol associations are stored in catalog files. There are three
catalog files as follows:
ALL.CAT
USER_V2.CAT
OUT.CAT
Resides in SIMetrix root directory. Stores catalog
data supplied with SIMetrix. SIMetrix never modifies
this file.
Resides in the application data directory (see
“Application Data Directory” on page 355). Stores
catalog data supplied by the user. Data in this file
overrides data in ALL.CAT. The Associate Models
dialog box writes to this file. In SIMetrix versions 5.2
and earlier this file was called USER.CAT. SIMetrix
will automatically import data from USER.CAT to
USER_V2.CAT if USER.CAT is present.
Resides in application data directory (see
“Application Data Directory” on page 355). This is
what is actually used by the parts browser to select
and place components. It is generated by the
associate model dialog box from information in
ALL.CAT, USER_V2.CAT and installed models. It
will also be automatically created by the parts
browser if it does not already exist. You can also
force it to be rebuilt at any time by selecting menu
File|Model Library|Re-build Catalog
File Format
Catalog files are text files. Each line provides data about a single device in semi-colon
delimited fields. The fields are as follows
Field 1
170
Device name as it appears in browser. This may optionally be
followed by a comma followed by the number of terminals for
the model
