Extracellular electrode arrays can reveal the neuronal network correlates of behavior with single-cell, single-spike, and sub-millisecond resolution. However, implantable electrodes are inherently invasive, and efforts to scale up the number and dens

The traditional approach to validate analog circuits is to utilize extensive SPICE-level simulations. The main challenge of this approach is knowing when all important corner cases have been simulated. A new alternative is to utilize formal verificat
