The symbol name is derived from the plating status, hole type, and drill diameter, using the
following syntax.
.bsm
Examples:
❑ PMTG125 – plated mounting hole 125 (mils) diameter drill
❑ NTOOL130 – non-plated tooling hole 130 (mils) diameter drill
The pad stack used in the board symbol may be derived from a pad stack mapping file, or
from a pad stack selection GUI. The mapping file — idxHolePadstackMapping.txt —
is a text file that maps the derived board symbol name to a specific pad stack definition. Each
entry in the file must contain two values. The first value is the derived board symbol name,
and the second entry is the pad stack used in the symbol definition.
Examples:
By default, the IDX import tool searches for the mapping file in the local directory, but you can
use the IDXHOLEPADSTACKPATH environment variable to point to a specific directory
containing the mapping file. The value of the environment variable is the directory path where
the mapping file is contained.
IDXHOLEPADSTACKPATH = /Cadence/mysite/pcb/settings
