• macro_gen Dev Log #2: Sizing Combinational Logic by Logical Effort 2026-09-29
  macro_gen now sizes arbitrary combinational CMOS logic by logical effort, relative to the inverter characterized in part 1, and buffers outputs to log4(F) stages. Method with a fully worked example, calibration of the model constants, and a comparison against SPICE on eleven SKY130 benchmarks.
