18:12:03 <ais523> kmc: VHDL, designed for modelling digital circuits, does indeed have 0, 1, Z, weak 0 (L), weak 1 (H), undefined (X), weak undefined (W)
18:12:14 <ais523> plus two more values, uninitialized (U) and don't care (-)
18:12:27 <ais523> so the "usual" boolean type in VHDL has 9 different values

20:51:00 <int-e> Hmm would Z be a floating state?
20:51:36 <int-e> (probably)
20:51:45 * int-e wonders more about the notion of weakness...
20:54:13 <int-e> Oh I have a guess: A weak zero will pull a line to zero, unless there's a strong 1 on it as well... so useful for busses.

22:12:10 <zzo38> Is it related to default logic?
22:12:25 <kmc> int-e: yes
22:12:51 <kmc> the usual hardware implementation is a pull-up or pull-down resistor
22:13:08 <kmc> that is, you connect the line to Vcc or ground through a large-ish (~10k ohm) resistor
22:13:45 <kmc> CMOS logic inputs are high-impedance; they only sense voltage, and draw minimal current
22:14:07 <kmc> so if nothing else is driving that line, its voltage will read at nearly Vcc / ground
22:15:45 <kmc> but if an output drives the line then the low-impedance output will form a voltage divider with the relatively high impedance of the pull-up/down resistor, and the resulting voltage is near the ideal voltage for the output
22:16:44 <kmc> (incidentally this is where "Z" comes from, Z is the symbol for impedance, and inputs / floating pins are described as "high-Z")
22:17:55 <zzo38> O, that is why they call it "Z".
22:20:07 <kmc> in terms of DC characteristics CMOS is pretty close to an "ideal" logic family; inputs are very high impedance, so they don't affect the circuits driving them very much, and outputs are very low impedance, so they can drive a lot of inputs at once (high fan-out)
22:20:46 <kmc> it's more complicated in another logic family such as TTL where inputs can end up sourcing or sinking nontrivial current at steady state
22:41:22 <arseniiv> juicy facts!
22:41:34 <arseniiv> is it known how much CMOS elements are in today’s circuits?
22:41:54 <arseniiv> more or less, in all of them, vs. other types?
22:49:36 <j4cbo> most things are CMOS
22:52:21 <arseniiv> that’s cool!

23:06:22 <kmc> yeah, CMOS became the dominant logic family in the 80s
23:10:23 <kmc> the trick is that making a CMOS chip requires fabricating two kinds of transistors (P-type and N-type MOSFETs) on the same wafer and getting good performance from both
