15. Digital Building Blocks (U instances)
U instances are digital primitives which may be used (in proper combination) to
model digital devices, e.g. from the 74xx or 40xx families. ngspice maps them
onto XSPICE models, which allows a fast event based simulation.

2.2. What are the latest features in the current release?
- New features:
+ Reduce XSPICE memory consumption dramatically
(> factor of 10).
+ Add source stepping to B source
+ Add 'esave' command to save only specific event nodes.
+ Accept '.temp=125' or .temp='param'.
+ Enable output redirection for meas command.
+ Use total current for diffcap calculation in diode model.
+ Speed output and reduces file size when plotting large
result vectors (Windows).
+ Enable RKM notation also for inductors (e.g. 1u2 for 1.2u).
+ Add S parameter simulation (command '.sp').
+ Add new flag 'digitop' for the 'plot' command.
+ Add a flag 'alle' (all event nodes) to the plot command.
+ New code model d_pwm: hybrid oscillator (analg control in,
digital out) with PWM.
+ Make "nogrid" plotting option work.
+ Add current measurement for all nodes of a device,
e.g. .probe i(Q1) will measure Ic, Ib, Ie (and Is).
+ .probe P(dev): Add measurement of power dissipation in a device.
+ Add new flags -type and -flags to command devhelp.
+ Add multiplier flag 'm' to behavioral capacitor and inductor.
+ Re-enable dc sweep after transient sim.
+ When plotting the phase, standard now is "Radiant".
+ Add Lundin's geometry correction to the inductance formula.
+ New variable keep#branch to write the current to raw file
in the old fashion 1 v1#branch current
+ Translate PSPICE U instances into equivaalent XSPICE code models.
+ New configure flag --enable-shortcheck to enable a shortened make check
(only BSIM3 and BSIM4).
+ B source will accept parameters in statistical functions like agauss.
+ WinGUI: Add a button 'Stop' to stop a simulation in intercative
or control mode.
+ Update to the .probe p (power measurement) and .probe alli commands.
+ Update to XSPICE aswitch and pswitch.
+ Make FROM/TO work in TRIG/TARG and WHEN variants of .meas/meas command.
+ Limits to exp function, allow 0 for log (returning -1e99), used
when starting iterations.
+ Insert XSPICE bridging devices automatically when an analogue node
has the same name as an XSPICE event node.
+ New options savecurrents_bsim3, savecurrents_bsim4, savecurrents_mos1.
+ pwlts: a pwl v/i source with time input, smoothing and limiting
functions.
+ New functions to the Code Model Library: cm_get_node_name()
and cm_probe_node().
+ XSPICE: Add bidirectional digital/analog bridge.
+ Search for .spiceinit firstly in a user defined directory named in env
SPICE_USERINIT_DIR, then in the current directory, then in HOME, then
in USERPROFILE.
+ If compatmode is lt, change the pow(x,y) and x**y functions:
If x < 0, output only if y is integer number, otherwise output 0.
+ Add a limit of 0.999 to bipolar parameters mje, mjc, and mjs.
- Bug fixes:
+ many bugs fixed and code improvements (see bugs 557 and up)
+ many bugs fixed and code improvements (see bugs 583 and up)

+ memory leaks removed
