3.4.1:
|
|
|
|
|
- Add more info in xschem_man about remote tcp connection
|
|
|
|
|
- Add mouse_bindings.tcl, courtesy Paul Bodenstab
|
|
|
|
|
- Make the "xschem_quit" command work (close current window / tab) also if
|
|
|
|
|
xschem started in -x (no graphics) mode
|
|
|
|
|
- Changed tcl procedure `setup_tcp_xschem` to allow setting a different port number for
|
|
|
|
|
further tcp commuication (and freeing the original port number)
|
|
|
|
|
- Enable xschem to load multiple files even if started with "-x" (only CLI mode)
|
|
|
|
|
- Add "show_infowindow_after_netlist" tcl variable (default = 0) that can be set in
|
|
|
|
|
xschemrc to always show erc window after netlist even without or no critical errors
|
|
|
|
|
- Added missing images for bus tap html manpages
|
|
|
|
|
- If a file is given on cmdline without any path qualifier (/.../, ./, ~/, ...) look into search paths.
|
|
|
|
|
- Apply center full zoom in all zoom full commands if tcl variable zoom_full_center is set
|
|
|
|
|
- Modify xschemrc file to avoid side effects if sourced (intentionally or by mistake) multiple times.
|
|
|
|
|
- Show red dot when cutting a wire with new alt-right button click on a wire.
|
|
|
|
|
Added also menu command in Tools
|
|
|
|
|
- Added command Alt-RightButton to cut a wire at mouse position.
|
|
|
|
|
- Do a prepare_netlist_structs(0) at end of break_wires_at_pins() for connectivity consistency
|
|
|
|
|
- Extended `Shift-M` command to selected nets (nets attached to them will stretch)
|
|
|
|
|
- Text elements with attribute name=xxx or floater=xxx will go through a tcl
|
|
|
|
|
substitution (instead of the translate(...) function if the referenced xxx
|
|
|
|
|
instance does not exist.
|
|
|
|
|
- floater=instname can now be given instead of name=instname (they are equivalent)
|
|
|
|
|
- Add new command `Shift-M`, move selected instances adding wires when separating
|
|
|
|
|
overlapping instance pins (Connect by kissing)
|
|
|
|
|
- Break_wires_at_pins(): delete piece of wires connected to symbol pins that extend
|
|
|
|
|
beyond the pin into the symbol
|
|
|
|
|
- Add command "Tools -> Remove wires running throuh selected inst. pins"
|
|
|
|
|
- Quit_xschem command
|
|
|
|
|
- Added commands `xschem switch [win_path|schname]`, `xschem destroy_all [force]`,
|
|
|
|
|
added `[force]` option to xschem exit
|
|
|
|
|
- Changed defaults in xschem: now toolbar and tabbed interface (more robust than multi-window)
|
|
|
|
|
is enabled by default, doc updates, improved fix_symbols for setting/removing path compoents
|
|
|
|
|
from symbol references, now uses low-level xschem reset_symbol (faster)
|
|
|
|
|
- Add procedure `fix_symbols <n>`to set `n` last directory components to all symbols in current design
|
|
|
|
|
- Added attributes spice_ignore=short, verilog_ignore=short, .... that will transform the
|
|
|
|
|
instance into a short in the current netlisting mode, shorting all pins to the same net.
|
|
|
|
|
Works similarly as lvs_ignore=short, but does not need lvs_ignore global setting
|
|
|
|
|
- Fix compare schematics if no file for schematic to compare with is given.
|
|
|
|
|
In this case compare current schematic with saved version.
|
|
|
|
|
Also issue a warning if swapping compare schematics if comparing schematic with disk version of itself.
|
|
|
|
|
- Added global tcl variable `lvs_ignore` that can be used to enable instance or symbol
|
|
|
|
|
attributes `lvs_ignore=open` or `lvs_ignore=short` while netlisting, added `test_lvs_ignore.sch` example
|
|
|
|
|
- Disable displaying backannotation data if `b` cursor is hidden or `Simulation->Live annotation
|
|
|
|
|
with b cursor` is disabled.
|
|
|
|
|
Use resolved_net() in translate() when displaying @spice_get_voltage so it will work on sub block ports
|
|
|
|
|
- Make `xschem exit` (ctrl-w, close window) work in multi-window mode exactly as in tabbed
|
|
|
|
|
interface, allowing to close the root window (will be swapped with subwindow and deleted)
|
|
|
|
|
- Save (ctrl-s function) normally does not save if no changes are made.
|
|
|
|
|
However if file timestamp has changed since opening (by someone else) prompt user to
|
|
|
|
|
decide what to do (save or not)
|
|
|
|
|
- Make ctrl-ArrowLeft/ctrl-ArrowRight work again (move to next/prev tab)
|
|
|
|
|
- Removed File menu commands `Empty schematic in new window` and `Empty symbol
|
|
|
|
|
in new window` since these just create another xschem process. Added `File->Start
|
|
|
|
|
new xschem process`. `xschem new_window` and `xschem new_symbol_window` commands removed,
|
|
|
|
|
added `xschem new_process
|
|
|
|
|
- Place polygon bind key is now `p`, ctrl-w is now `Close current schematic`, while ctrl-q is
|
|
|
|
|
`Quit xschem`. Reorganized File menu, added more orthogonal `Create new schematic/tab`
|
|
|
|
|
removed some largely unused entries. Ctrl-w does not close the last window, just leaves it blank.
|
|
|
|
|
Use ctrl-q to close xschem
|
|
|
|
|
- Removed some direct exit() calls in editprop.c
|
|
|
|
|
- Cleaner exit if xschem -v is given
|
|
|
|
|
- Cleanup exit procedures: tcl exit command will cleanly delete additional tabs/windows
|
|
|
|
|
data structures before closing
|
|
|
|
|
- Add command xschem tab_list, returns window pathname and associated filename loaded
|
|
|
|
|
- @spice_get_voltage: do not process if net is a multiple bit bundle
|
|
|
|
|
- xschem resolved_net command: add [net] parameter
|
|
|
|
|
- Fix long standing bug: redundant grammar rule in expandlabel.y causing it to fail
|
|
|
|
|
recognizing nodes like GND*16
|
|
|
|
|
- Add more ".." bus notations: XX[4,2,8..1..3,12,23] and others.
|
|
|
|
|
- Implementation of portmap feature: from sub-schematics resolve hierarchic name of schematic
|
|
|
|
|
nets connected to I/O pins (go to the upper level recursively until resolved)
|
|
|
|
|
- Enable rainbow colored graphs also for double dc sweeps
|
|
|
|
|
- Update n and p jfets, added pjfet simulation
|
|
|
|
|
- Allow @#n:pin_attr or @#pin_name:pin_attr in verilog and vhdl format string (print_vhdl_primitive,
|
|
|
|
|
print_verilog_primitive), in addition to @#n (convergence to translate()
|
|
|
|
|
- Improved "xschem display_hilights [nets|instances]" that displays highlight nets or instaces or
|
|
|
|
|
both,with full hierarchy path, not including uninteresting net/pin/net_show elements.
|
|
|
|
|
- Bus_tap.sym symbol for true bus tap (slice some bits out of a bigger bus).
|
|
|
|
|
|
|
|
|
|
3.4.0:
|
|
|
|
|
- Added xmag and ymag entry boxes in grapg dialog box to allow user change of x/y label text sizes
|
|
|
|
|
- Replace @symname in instance "schematic" attribute with basename of symbol
