was previously (and erroneously) lumped with PLACED and FIXED which
take a position argument afterward. Note that this fix allows the
DEF file to be read without error but does not have the (presumably
desired) behavior of parsing SITE information from the LEF file and
ROWS information from the DEF file and giving each unplaced component
an arbitrary but legal position. That would require a significant
amount of additional coding work.
while reading DEF. To preserve names as much as possible, such
names are now kept. To avoid problems, EFbuild.c and ext2hier
behavior has been changed to only parse entries in a .ext file as
instance arrays if the array notation follows the specific syntax
of [ax:bx:cx][ay:by:cy], letting all other uses of brackets pass
through unaffected.
sure if this is the best policy. The brackets should be okay
but interfere with ext2spice when it reads them from the .ext
file and decides that they refer to arrays. May be a better
way to handle this.
forms of syntax found in the LEF/DEF spec up to version 5.8. Handles
vias formed by parameter and a number of syntax variations that mess
up the usual parsing. Corrected an error in the calculation of wire
extensions when wires are given with three coordinates.
discovered that not all LEF/DEF rectangle coordinates are in
canonical order. Took the opportunity to update the LefError()
routine with an additional argument so that it can separate
errors, warnings, and informational messages, and will correctly
state whether the output is for a LEF or DEF read operation.
(once corrected in an experimental branch but never merged). This
avoids changing the actual bounding box of the cell to match the
LEF bounding box, but defines a property instead and uses that
property for certain functions such as displaying the bounding box
outline or selecting the cell. This avoids certain related errors
such as the failure to extract connections to areas outside of the
fixed bounding box.
label in a DEF file is on a layer that has not been properly
mapped to a magic layer. This would apply a negative index to
a TileType bitmask and crash the program. Also: Changed the
style and colormap slightly to make the via2 and via4 styles
more visible.
development had been halted since it was first created back in April.
Version 8.2 is now the official development version, with the first
development push to create a Cairo graphics interface.
