RDS_IN sets the physical real input file format of the rds data structure. The data structure will be filled with informations found in the given format files.
valid formats are :
- cif, caltech intermediate file format
Some cif standard extensions are known :
9 name;
defines the name associated to the Define Symbol
construct.
4A x0 y0 x1 y1;
describes the abutment box of a model. see mbk(1)
for more on abutment box. x0, y0, x1, y1 are
respectively the lower left corner, and the upper
right corner of the abutment box.
4I instancename;
assigns a name to a Call Symbol.
4X connectorname width x y; defines the pin called connectorname, at x,y location, with the given width. This doesn't define a rectangle.
4N nodename x y;
gives a name to every object from the current layer
that include the given point.
None of those extensions are generating layout, so a
tool that skips cif extension will still have a correct
and complete layout.
The licit objects are square polygones, with angle multiple of 90
degrees. Circles, triangle, and other exotic objects, are strictly
forbidden. You shall ensure that your real pads follow these rules
before parsing them.
The variable default value is ``gds''.
RDS_IN : `xxx' unknown format"
The argument given to the setenv is not a legal layout input format
for rds. You must changed it before any other action.
setenv RDS_IN gds
s2r(1) , RDS_OUT(1) .
This tool is under development at the ASIM/LIP6/UPMC laboratory, cao-vlsi
