is found, then the tool renumbers the RefDes coming from the
block.
o Prefix
This is used to assign a prefix to the reference designator of the
components of the block.
For example, if you specify the Prefix to be K, then the RefDes
for that instance would change from say U10 to UK10
o Suffix
This is used to assign a suffix to the reference designator of the
components of the block.
For example, if the value of suffix is specified as _K, then the
RefDes for that instance would change from say C01A1 to
C01A1_K
o Offset
This is used to specify an offset value for the RefDes and the
components of the block will have this value added to them to
create RefDes.
For example, if offset is set to 30, the RefDes would change
from U12 to U42.
This option can only be used when the directive
REFDES_ALPHA_NUM is set to NONE.
o Use Range
This option is used to specify a range for the RefDes of the
components of a block.
For example, if the range is specified as 501 to 600, the
components from this block will have RefDes assigned from
501 to 600.
o Pattern
This option allows you to define any custom pattern for RefDes
naming. The pattern can have multiple variables assigned
which the user can provide value of at the time of application.
By default, there are two variables, USER_STRING and
