window in the toolkit, which was to the "tkwait" command, which
waits for a change in state. What was intended was to wait for
a change in state to visible only; once visible, the "tkwait"
command should not invoked or else the process will block.
(truly) missing a terminal (such as a MOSCAP made with a gate
extending into but not crossing a diffusion region). Added the
most requested GUI feature, which is a vertical scrollbar on the
parameterized device window (could be improved by maximizing
window height without exceeding display height).
that the feature for implementing callbacks on a selection list
was already implemented via the add_dependency procedure.
Modified the GDS read to remove cell instances that are placed
directly on top of one another in the same cell. Modified the
GDS read to make a better selection of a default font size for
text that specifies a font but not a size, using the minimum
width for the layer the text is placed on. Modified the GDS
read to remove text with empty-string placeholders (created when
a pin layer is read but no text exists to go along with it, due
to GDS not having a specific way to make pins, such that pins
have to be split between one record for geometry and another
for text).
optional argument that is a callback function, so that the act
of selecting something from the drop-down menu can cause things
to happen such as changing the GUI window contents for the item
selected.
conversion, largely converted from the python script in open_pdks,
which itself was derived from an efabless script, and none of
which have been particularly well tested.
Instead of a 6-character suffix generated randomly, the 6-character
suffix is generated by a hash algorithm from the device parameters.
If the cell parameters are changed, then the cell itself changes.
If the instance name was default (derived from the cell name) then
the instance name changes accordingly. The result is that there
cannot be two (auto-)generated cells with the same parameters but
with different cell names.
the bottom in non-interacting areas means that any change in DRC
to a subcell must be handled before checking DRC in the parent.
Previously the order of checks was reversed, moving parent cells
to the beginning of the check list. This prevents the error cited
in the previous commit which was showing up as a delayed DRC check
when creating parameterized cells.
processes "interaction areas". This should eliminate weirdnesses
where errors will fail to show up in a subcell that does not
interact with paint or other subcells in the top level edit cell.
These errors cannot be reported directly in the top level cell,
but a new error message has been created to direct the user to
check the subcell for errors. Also: Modified the toolkit procedures
to force DRC to be run on newly created or modified parameterized
cell layouts. There is some oddity about the process that causes
DRC errors to be delayed unless a print statement is put before the
DRC check; I would like to investigate this further.
from a selection, which can then be used to index into other lists.
This lets one selection be made on a list of arbitrary names, and
then additional parameters can be linked together with the same
index). Also, implemented (finally!) the "offset" parameters of
the "slots" function (as advertised in the documentation).
