"timestampEdited": null, "callEndedTimestamp": null, "isPinned": false, "content": "Sooo.... yeah, for DC behavior of SCL cells and selected primitives the \"muxed e-test\" should fairly straight-forward be applicable, and the \"version\" without reaching for extended voltage range should also be fairly compact and straight-forward.\n\nCapacitance is unfortunately not a direct derivative from it, and not something that can be measured with good accuracy and effectiveness without setting up/arranging for up-front SPICE predictions of the actual AC impedance expectations at the frequencies and DC bias conditions (incl. the PVT parts) where the AC impedance/\"capacitance under not-neglecting resistive parasitics\" should be measured.\n\nRing oscillators, potentially with various combinatorial logic (that can be flexibly configured to allow excercising many more transition paths than a combinatorially entirely trivial setup could) in the oscillation's feedback/ring loop, appear the most promising substitute to actual \"direct\" AC capacitance measurements of DUTs under e-test conditions subject to the same boundary requirements as the \"muxed e-test\" of DC-behavior type.\n\nWhere dynamic power needs to be measured, isolate PDNs sufficciently and employ muxed e-test measuring with 4-wire kelvin configuration for this;\notherwise, set up ring oscillators that can be configured with statically decoded control lines (serially shifting in select/control bits is quite annoying to arrange for in an e-test setup, compared to performing DC multimeter measurements and select instances of frequency counting), such that only the small ring around a DUT is oscillating (into a divider reducing it as far as necessary to allow easy measurement with an off-chip frequency counter).\n\nControl lines can of course \"recycle\" a DUT in a ring for multiple transition paths of interest by adjusting other/non-ring inputs of the involved cells.\nThink a simple `NAND` or `NOR` gate in the loop blocking edge propagation when not selected, based on whether the path in question needs an extra inversion or not; there are probably a bunch of practically interesting \"critical path\" combinatorial arrangements that can be measured/excercised in practice here.\n\nSplitting/isolating supply voltages between paths of a single ring to allow individual dynamic power measurement and keeping the ring to as few transistors as practical should allow affordable SPICE-fitting of local mismatch modeling's random variable's individual values to squeeze out decently targeted calibration of capacitance/AC-only model parameters by taking the previously run \"muxed e-test\" data of dc behavior and statistical distribution of the local mismatch effects for those involved SCL cells (and of course the transistors making up those SCL cells!) as a Bayesian prior, to spend the much worse data situation of the ring oscillator setups focused on improving calibration of the capacitance/AC-only SPICE model parameters rather than wasting that measured data on parametrizing the statistical distributions of the SPICE model instance parameters (||those are basically global model parameters tweaked by binning consideration effects, as applicable local surrounding geometry/mechanical-strain effects, and critically local random mismatch effects from e.g. statistically random countably-small-number-of doping atoms in the electrically sensitive region of a tiny SCL transistor||) that describe the DC behavior.\n\nEven without such effort of calibrating primitive-device's SPICE models to ring oscillator measurements, it should be effective for calibrating cell-granularity (as suited for Liberty timing spec synthesis) propagation delay well enough for reliable static timing analysis.", "author": { "id": "262706220073222144", "name": "namibj", "discriminator": "0000", "nickname": "namibj", "color": null, "isBot": false,
