xschem-2.9.7.tar.gz updated to [r526]. See README.TXT for details.

- store symbol wires (if any) as Instdef lines on layer WIRELAYER (1) so they are visible when instances are placed.
- spice netlister: if ".param m=10 n=5" is given and "R1[m:n]" instance name is present resolve parameters
  and replace instance name with R1[10],R1[9],...,R1[5].
- Fix: zoom_box function called from menu was broken
- tcl proc probe_net: if <path>.netxxx is given where xxx=number then try first probe netxxx, if no net is found try #netxxx
- load system-wide xschemrc first, then $PWD/xschemrc or ~/.xschem/xschemrc; user xschemrc appends to
  system-wide xschemrc instead of replacing it.
- verilog_netlist: use name "top_schematic.sym" from "top_schematic.sch" before calling
  load_symbol_definition for verilog parameter netlisting
- fix to avoid name chashes between auto-named nets (#net<number>) vs user set net names (net<number>)
- device_model attribute: allow escaped quotes in text
- allow .subckt as well as .model in device_model attribute, even with identical model/subckt name
- "device_model" attribute set in symbol or symbol instance may be set to a SPICE .model
  specification (device_model=".model D1N4148 D ...").
  This model will be printed only once per component at end of netlist.
- "xschem clear SCHEMATIC" incorrectly sets untitled.sym file name. Thanks to Neil Johnson for pointing out the issue
- add --tcp_port command line option
- added (optional) tcp server that can be used to accept commands from other applications (backannotation, cross-probing)
- added video tutorial on cross-probing into GAW
- added "Simulation->Send highlighted nets to GAW (Alt-G)" to probe xschem nets into an open gaw window
  using gaw ttg socket commands.
- dircolor variable (associative array) in xschemrc to set custom user defined colors for xschem
  component/schematic libraries: "set dircolor(path_regex) color"
- glob filter (all, .sym, .sch) in file open dialog.
- created command "Simulation->Create ngspice xplot probe file", this creates a xplot script
  for ngspice with waveforms of same color as highlighted xschem signals.
  Fix a problem in verilog_netlist.c not writing "---- begin/end user architecture code"
  blocks if empty user architecture. This confuses verilog.awk post processor.
  added logic/ram_tb.sch verilog example.

xschem-2.9.6.tar.gz updated to [r482]. See README.TXT for details.
Mostly a bug fix over 2.9.5
Changelog
2.9.6
- filled arcs/circles in svg and pdf exports
- fix segfault when selecting polygon on layer x close to circle on layer y: incorrectly returning polygon on layer y
- fill=true attribute for arc/circles, same as for polygons
- add "--script <tcl_file>" to allow executing a tcl script from cmdline
- allow flat netlist with LVS flag set
- fix crashing bug: check for missing "name=" attribute on symbol pins in sym_vs_sch_pins()
- separate "spiceprefix" and "toplevel is a subcircuit" options, move under Simulation menu
- In load_file_dialog(), when the LHS panel is root, going down on the RHS panel should not
add an extra / for the new directory name (applicable to both Linux and Windows)
- catch open filename should be within quote to handle window's filename with spaces;
- @spiceprefix added in front of @name in nmos4.sym, pmos4.sym, pmos.sym and nmos.sym in devices/
- fix clash in loop variable in sym_vs_sch_pins()
- better erc check: sch_vs_sym pin check in addition to sym_vs_sch
- merge-in windows changes into xschem.tcl
- vhdl postprocessor: add _vector on bussed nets only if boolean, integer, real, bit or std_logic type.
Do not add for any other user defined type
- vhdl netlister: do not declare record field signals (signal mysig.myfield), print component declaration
for symbols with type=primitive
- Windows porting code added.</tcl_file>

xschem-2.9.5.tar.gz updated to [r449]. See README.TXT for details
added library gschem_import and gschem_import/sym with all gschem example circuits and symbol library translated for xschem by using gschemtoxschem.awk script.
simconf simulation configuration tool
schematic/symbol preview window
Hilight subcircuit symbols during netlist if there is a pin mismatch with underlying schematic
preserve instance name up to numeric index when copying instances and 'Allow duplicated instance names' is not active: DIODE1 --> DIODE2 instead of D2
lock=true attribute makes component unselectable (good for page title )
ngspice raw file to vcd converter so gtkwave can be used for analog sims (rawtovcd)
better open / insert file browser dialog
New eeschema-like bus notation DATA[0..3] expands to DATA0,DATA1,DATA2,DATA3, this differs from xschem standard notation DATA[0:3] that expands to DATA[0],DATA[1],DATA[2],DATA[3]. Complex notations allowed like DATA[0..3],2DATA[7..4],CS,CLK,RST,VCC3 for funky bundles.
warnings when opening a non xschem file or placing a non symbol file.

c89 portability: eliminated snprintf, strtok,strtok_r, Variable length arrays,
getopt,
more error checking on malformed input fieles
added circles / arcs to pdf export
better window titles
untitled.sch default file name if xschem launched without a file name.
long options (--version, --help, etc)

XSCHEM is now part of coralEDA, an umbrella project collecting open source EDA tools aiming to inter-operate together with common protocols.
to get the most up to date go here.
To get the most up to date development checkout from svn:

xschem-2.8.0 updated to [r93]
- draw connecting dots automatically on T or Y connected wires,
- new commands in Tools menu to trim and break wires
Break wires will break selected wires at instance pin / other net connettions.
Trim wires will resolve overlapped nets, join parallel nets, etc.
- .xschem/ directory for private data and config files.
- initfile renamed, from .xschem to .xschem/xschemrc
- XSCHEM_HOME_DIR renamed to XSCHEM_SHAREDIR (sharedir in Makefile)
- added USER_CONF_DIR (Makedile userconfdir) (~/.xschem)
- XSCHEM_DESIGN_PATH renamed to XSCHEM_LIBRARY_PATH (makefile xschem_library_path)
- make xschem work correctly with all combinations of HAS_XCB and HAS_XRENDER
- optmizations in update_conn_cues()
- no recursive functions for deleting hash tables.
- simpler loops for iterating rectangles that contain a wire in spatial hash table.
- different location of startup user rc files: .xschem/xschemrc instead
of .xschem
- deleted utile junk old files
- xschemrc moved under src/

xschem-2.7.0 updated to [r91]
- some fixes in library path management (abs_sym_path and rel_sym_path in xschem.tcl)
- documentation updates on required -dev files, libfl-dev and cairo2-dev
- documentation updates on open/closed polygons
- embedded symbols, (embed=true attr on instances), documentation updated.
- Status bar grid entry configured as disabled as it is output only
- make xschem accept some malformed input files, like T{} ... or leading spaces before element tags.
- code in place for command to cut wires at instance pins and intersections
- created iterator function for spatial wire & inst hash tables to avoid
code duplication
- removed exec flag on all doc/ files, moved xschem.html to index.html
- keep calculating bbox for unusually big texts, even if these text are not
displayed being fonts too big (crash on old cairo libs)
- corrected menu accelerators shown for zoom / unzoom.
- unzoom_nodrift tcl variable can be set to 1 or 0 to produce slightly
different unzoom behaviors.
- flush arc drawing routines (draw[temp]arc(END,...) in addition to lines
and rectangles when doing selections /hilight. (forgotten since arcs
were introduced).
- nets are drawn after the other elements so they are always on top.
- new xschem TCL commands
- xschem setprop instance x25 w 55
replaces property w of instance x25 with new 55 value
- xschem setprop instance_n 123 w 55
same as above but indicate instance number (position in inst_ptr array)
- xschem replace_symbol instance x25 .../../new_symbol.sym
replaces symbol of x25
- xschem replace_symbol instance_n 123 .../../new_symbol.sym
same as above but indicate instance number (position in inst_ptr array)
- new commandline option '-i' to tell xschem not to load init files (xschemrc and .xschem)
- order coordinates before storing nets in load_wire(),
for some reason this trivial thing was missing
- drawing glitches fixed
