3.4.5:
- If a full path is given with -N set netlist file name as well as destination path
- Handle TABs in draw_string() (also ps and svg draw_string()),
tcl var tabstop (default = 8) sets the tab positions.
- Added command `xschem cursor 1|0 1|0` to enable or disable cursors via cmdline
- Add command `xschem swap_cursors`
- If top level schematic has an associated symbol (.sym) file ensure their ports match, otherwise
issue an error. if netlisting fails return non zero exit code if netlisting from command line
- Add @#pin:spice_get_voltage attribute for pin texts that displays voltage of net attached to pin.
Remove net_name=... attributes from symbols and instance global attributes since it is no more used.
set default value for show_pin_net_names to 1.
- xschem image rectangles: allow to fetch urls using filter="tcleval(wget --quiet http://.... -O -)" and image=""
- xschem wave processor: added <, >, <=, >=, ==, != and contitional ? (3 operands) operator
- Added drc_check() function, that evaluates tcl scripts contained in symbol `drc` attribute.
Used for checking allowed dimensions, mostly
- Add ellipses (rectangles with attr ellipse=1)
- Add simulation->graph menu for auto_hilight_graph_nodes
- Add `Tools->Grab screen area` function (unix only)
- fill=solid in addition to fill=1 (stippled fill) or fill=0 (no fill) for rectangles,
polygon/beziers and circles
- Added dark_gui_colorscheme (default: 0) for dark widget colorscheme configuration.
- Added intuitive_interface xschemrc and menu option: click and drag to quickly
Move objects without keyboard commands
- Bezier shapes can be drawn (polygon with attribute `bezier=1`)
- Add tcl tabulate procedure for pretty encapsulating tabular text into a nice ascii table frame.
- Add `xschem raw del node` command
- Add option `keep_symbols in xschemrc to avoid purging symbols when netlisting /descending hierarchy.
- Add functions atan, asin,acos, cosh, sinh, atanh, acosh, asinh, idx in wave processor
- Added command `xschem raw new name type sweepvar start end step` that creates an
in-memory plot (like a loaded raw file) with only the sweep variable
- Extend command `xschem raw_query add [expr]` for fast (C-speed) expression calculation
- Add command `xschem raw_query add <node>` to add a vector <node> with all zeros to the
loaded raw file. This vector can then populated with programmatic values using
`xschem raw_query set <node> point value` loop
- Add command `xschem raw table_read table_file` to read an ascii table file without closing
other loaded raw files
- Add xschem list_nets command
- Preview window in file open dialog box is x/y resizable
- Parametric models in subcircuits (model=@mod in instances, mod=xxx in parent instantiation)
- Instance based schematic selection: if instance specified schematic=... not existing
Use base schematic (symbolname.sch)
- Add verilog_extra_dir symbol attribute to allow specify "ports by attribute" directions:
verilog_extra_dir="VCC=input GND=input" verilog_extra="VCC GND" extra="VCC GND" ....
instead of the default ~/.xschem/simulations. Changed background color of menu radiobuttons for clarity.
- Allow parametric models in subcircuits. Symbol inv.sym contains template="... modp=cmos_p_10 ...",
pmos instance in inv.sch contains model=@modp, instance format string contains
format="@name @pinlist @model w=@w l=@l, result is: "m2 y a VCCPIN VCCPIN cmos_p_10 w=wp l=lp"
- pass instance `device_models=...` attribute through translate() so @vars are resolved
- added `xschem fill_reset` command to reset fill patterns defined via tcl array pixdata(n)
- add `hide=instance` attribute for in-symbol text objects (in addition to hide=true or hide=false).
If set the text is in visible in instantiated symbols, but is visible if descending into the symbol
- When doing spice netlist, if a symbol has the spice_sym_def attribute set and is using @pinlist
in format string for port order, get the port order from the subckt given in spice_sym_def,
either directly or through a .include line
- xschem raw_read: allow specifying t1 and t2 to load only a portion of simulation file
- Implement vertical flip (shift-V) and vertical flip in place (alt-v)
- Handle xyce y-devices in spice netlists
- Setting line width in View menu will automatcally disable change line width with zoom
- If selection is present when exporting pdf assume it is a bboxed pdf
- Add xschemrc option ps_page_title (default: enabled, 1) to set or hide page title in ps/pdf exports,
more precise graph exports in svg and ps/pdf
- Add `xschem set cursor[12]_x` commands for moving graph cursors
- Add `xschem set hilight_color` command
- Allow instance attribute `text_size_n=s` (where s is a double and n is an integer) to set
symbol text item `n` to size `s`
- When doing spice netlisting if top level has a symbol (and the symbol has i/o ports) use the symbol
for printing the top level subckt port list. This ensures same port ordering when netlisting
a testbench containing a component and netlisting the component itself.
- Add tanh(), min() and max() clipping functions in wave calculator
- Change Waves button to menu entry with various options (annotate OP, load tran, dc, ...)
- Add make_sym_from_spice.awk, cut down from make_sch_from_spice.awk
- Add command `xschem setprop text n txt_ptr value` to change a text object text field
- Add tabs bar context menu
- Add option --pipe (alias for -r / --no_readline)
- Dragging to the right a selection rectangle will select objects fully enclosed.
Dragging to the left will select all objects intersected by the select rectangle.
- Add context menu entries for rotate and flip selection,
- Add basic sub-process control in Simulation menu.
- add @symref attribute that resolves to the full symbol reference as specified
in instance: example: "sky130_fd_pr/pfet_01v8_lvt.sym"
- Add the ability to load multiple raw files with different analyses in
a single schematic ( extra_rawfile() ).
Allow loading more and different analyses from the same raw file.
- Transform multiple saved OP sims into a dc sweep.
- Do interpolation when annotating "b" cursor values in schematic,
as done with measurements with "a" cursor.
- Cursor `a` measurements in graph match the %n dataset specified on nodes
if any (or default to dataset 0)
- Update live backannotation if "a" and "b" cursors are swapped,
- syntax node%n is now allowed to plot only dataset "n" of
the node.
- add `lock` attribute for rectangles: work the same as for instances
(can only double click to reset attributes, not selectable until lock reset to 0).
- Add commands "xschem selected_set rect" and "xschem select_inside x1 y1 x2 y2
- Add rotate, flip menu entries in the Edit menu
3.4.4:
- First selected instance is now always the master (instead of the first in the
xschem array order) when doing an edit attribute on a group of selected elements
