+SAR ADC dynamic comparator on PSP103, charge swamped by 1e6: backward Euler on a fixed 0.1 us grid
+* specs/analog/decks/sar_cmp_psp_r2.cir -- reference data for specs/analog/sar_comparator_psp.t27 (analog M4b-psp, #10856, epic #10486). A netlist plus a

+* Circuit: the subcircuit dynamic_comparator of the uberWAVE golden SAR deck (wp2-parser/golden/top.spice; GPL-2.0, fetched at run time, never vendored),
+* thirteen sg13_lv transistors and the inverter x1 that makes n_clkc, PSP103 (IHP-Open-PDK 21133f219b1a6da10d803e345761e77415ceff40, cornerMOSlv.lib
+* mos_tt, through OSDI), at 50 C, the temperature of the golden deck. The deck reads the subcircuit text from the file named by the environment
+* variable SAR_GOLDEN_SUBCKTS, the subcircuit section of the fetched deck without its .end and .global lines:
+*   sed -n '/^.subckt tracking_switch/,$p' top.spice | grep -v -i -E '^\.(end|global)([[:space:]]|$)' > $SAR_GOLDEN_SUBCKTS
+* ngspice reads IHP_PDK (the IHP-Open-PDK checkout), IHP_OSDI (the directory with the compiled psp103.osdi and psp103_nqs.osdi) and SAR_GOLDEN_SUBCKTS.
+* Run: IHP_PDK=<checkout> IHP_OSDI=<osdi dir> SAR_GOLDEN_SUBCKTS=<file> ngspice -b sar_cmp_psp_r2.cir > sar_cmp_psp_r2.out    (ngspice-47)
+* THE SCALE. PSP103 has charge: gate and junction capacitance of the thirteen devices (m up to 36, a few hundred fF on a node) which the current tables
+* of the spec do not have. To compare the CURRENTS alone, the lumped node capacitances of the spec (4 fF on ap, an, dp, dn; 6 fF on net1; 2 fF on
+* net2, net3, n_clkc) are multiplied by 1e6 (4 nF, 6 nF, 2 nF) and the step by the same 1e6 (0.1 ps becomes 0.1 us), so dt / C is the spec's, and the
+* devices' own capacitances, a few hundred fF, are 1e-4 of the 4 nF at the largest. The currents are the real ones. Between 1e4 and 1e5 the decision
+* time moved by 0.83 % and the resolution time by 1.3 %, between 1e5 and 1e6 by a tenth of that: the charge left at 1e6 is about 0.01 %.
+* Inputs: VDD 1.5 V, common mode 0.75 V, VDP = 0.75 + sg h / 2^24 and VDN = 0.75 - sg h / 2^24 for h in units of 2^-24 V (the spec's words: h = 16777 is
+* 2h = 33554 units = 2 mV less 0.4 uV) and sg = +1 or -1. The clock is a B source of nint(time/dt): 0 for the first 10 grid points, then a ramp of 16
+* steps of 1.5/16 V, then 1.5 V. Start: from .ic and uic, ap = an = net2 = net3 = n_clkc = 1.5 V, dp = dn = 0, net1 = 0.4009999632835388 V (5872026 units, the
+* spec's max(VDP, VDN) - 0.35 V rounded to a word, an initial condition and not PSP103's own rest: net1 floats and an operating point would put it at
+* 0.71 V on gmin). Integration: gear with maxord 1 is backward Euler, trtol 1e7 stops the truncation test from shrinking a step; reltol 1e-7, vntol 1e-10,
+* abstol 1e-12, gmin 1e-12 (at 1e-9 / 1e-12 ngspice aborts at the first clock step). 150 grid points: step j of the spec is the row of the grid point j + 10.
+* What it prints, per run, after "RUN <h> <sg>": tck, the clock through 0.75 V; tfirst, the first output through 0.75 V; tres, |dp - dn| through 0.75 V
+* (those two are absent when the run does not reach it); dpend and dnend, the outputs at the last point; then eight rows "<row> v(ap) v(an) v(net1) v(net2)
+* v(net3) v(dp) v(dn) v(n_clkc)" at the rows 39, 59, 71, 79, 87, 95, 109, 149 (steps 20, 40, 52, 60, 68, 76, 90, 130: ngspice's opening ramp puts nine rows before the grid, so

+SAR ADC dynamic comparator on PSP103 with every bulk tied to its source, charge swamped by 1e6: backward Euler on a fixed 0.1 us grid
+* specs/analog/decks/sar_cmp_psp_r2b.cir -- reference data for specs/analog/sar_comparator_psp.t27 (analog M4b-psp, #10856, epic #10486). A netlist plus a
+* .control block that prints the numbers. The same run as sar_cmp_psp_r2.cir (read its header for the scale, the inputs, the clock, the start, the
+* integration options and the printed rows) on the same thirteen transistors and the inverter x1, with ONE change: the bulk of every device is tied to its own
+* source, which is what a 2-D table Id(Vgs, Vds) of M3b models. The golden deck ties the NMOS bulks to ground and the PMOS bulks to VDD, so the input pair
+* XM3, XM4 (source net1, 0.15 .. 0.4 V above its bulk) and the PMOS XM8, XM9 (sources net3, net2, below their bulk) carry a body effect which the
+* tables cannot have; the difference between this deck and sar_cmp_psp_r2.cir is that body effect and nothing else. W, L and m are the golden deck's
+* (facts of the circuit); the text of the golden deck is not copied. The deck reads no golden file: IHP_PDK and IHP_OSDI only.
+* Run: IHP_PDK=<checkout> IHP_OSDI=<osdi dir> ngspice -b sar_cmp_psp_r2b.cir > sar_cmp_psp_r2b.out    (ngspice-47)
+* Second part, "MM <m4> <d>": the input pair made unequal, XM4 (the device whose gate is VDP) at m = 35 and 34 instead of 36, with VDP - VDN = d units of
+* 2^-24 V; it prints dpend and dnend only. The flip point of the unequal pair is the d at which the winner changes: dn wins below it, dp above. The
+* four d are the pairs of neighbours found by bisection (a 2-unit bracket): 71579 and 71581 for m = 35, 145772 and 145774 for m = 34.
