Cldm adds the layout description of one or more
cells (models in LDM) to the ICD database. If a cell
description is read, cldm creates a new cell
directory, and translates the LDM cell description into an
internal database format.
The cell descriptions are read from the specified LDM
file and must be the last argument. In most cases a file
with suffix ".ldm". The input must be conform the
syntax rules of LDM. If not, a syntax error will be the
result, and an appropriate error message will be
generated.
To help you in making a correct cell definition you can
invoke cldm with option -s. In that case cldm
performs only a syntax check, and two kinds of semantic
checks, i.e.:
1) a cell may not be redefined,
2) a cell called in a cell description must already exist.
With the origin mode (option -x) the lower-left corner of
the bounding box of a sub-cell is used as the translation
vector reference point. Note that if the input file for
cldm was obtained with xldm, the option -x
should only be used if and only if it was also used with
xldm.
If an error is detected the cell will not be added to the
database. This can result in subsequent error messages,
complaining about the fact that the cell does not exist.
