information that is in the Virtuoso Layout Migrate technology file. In
fact, most of the information in the qtt file isn't even in the DFII
techfile (yet).
Just like you wouldn't necessarily derive an Assura or Calibre rule
deck from the DFII technology file, you don't necessarily have all the
data points you need for a layout migration or optimization or eco in
the DFII technology file.
However, there is a simple AE ware (undocumented unsupported) 300-line
PERL script, tf2qtt, that creates a boilerplate qtt file from an ASCII
dump of the DFII techfile.
In addition, Customers should press their CDK vendor to supply the qtt
file (for now) in the CDK pdk vlm directory. For example, I just
looked in the latest Cadence generic 90nm CDK (CDK090_v1p0p7) which
contains the following directory tree:
CDK090 / pdk090 / vlm090 / gpdk090.qtt & gpdk090_migratemap.il

pdk === process design kit (enough to run all desired custom
tools)
