a long-standing error (introduced with the "extresist geometry"
option) that can cause nets not to be extracted (due to the first
record not having extraction data, which was itself a long-standing
error in the code but which was not fixed correctly); (2) handle
"device mosfet" type transistors (previously only handled the old
"fet" type extraction devices); and (3) correct for the res.ext
file having a different scalefactor relative to the .ext file. The
latter item was solved by forcing all input to scale like
ExtCurStyle->exts_unitsPerLambda, locally correcting all input as
needed. Note that extresist still needs to handle other extraction
devices (e.g., resistors and capacitors) but those will require
additional handling in the routines which analyze the current path
to determine how to break up wires into paths.
with ext2spice without the hierarchy option. More work needed to
produce correct hierarchical output and to support extraction
devices other than the old "fet" record.
simple FET device in extresist. Also: Extended the bloat-all CIF operator
again, allowing the trigger layer for the bloat operation to include both
CIF layers and magic layers (previously only magic layers were supported).
This extension is possible due to the previous extension allowing the
trigger layer and bloating layers to be on separate planes. This operator
extension is useful for tagging geometry that is in the proximity of, but
not overlapping, geometry on another plane.
hierarchical cells (namely a scaling issue with .sim file units).
More can be done to make the extresist command more user friendly,
but at least port connections as drivers appears to work.
to be more robust and not depend on the ordering of the devices in
the techfile. The extraction method now keeps a mask of which
properties of the device (source/drain types, substrate type,
identifier type) have been found, and will look only for device
records that match what is known about the device. Added a device
identifier record which is the last record before parameters if the
record begins with "+". This allows marker layers to be placed
over a device such that it will extract with a different type.
This helps reduce the complexity of the techfile and allows
certain specialized devices like RF or ESD to be identified without
a separate layer type for the device.
