WebMar 16, 2024 · To fix the problem, as you have already figured out by yourself, just replace out.backward (z) with out.backward (), which is equivalent to out.backward (gradient=torch.tensor (1.)), since in your case out is a scalar and f (out) = out, so d [f (out)]/dout = d (out)/d (out) = tensor (1.). WebOr does the mismatch simulation reflect the case of arbitrary placed components all over the wafer (or over a certain layout area)? In this case, an optimized layout (centroid + dummies, etc.) would cause less mismatch than simulated. For example, if one designs a R2R-DAC and the mismatch-simulation shows that all specifications are fulfilled.

WebThe gradient mismatch problem also exacerbates as the er-ror signal propagates deeper down the network, because ev-ery time the presumed g0(a(l) i)is used, additional errors are introduced in the gradient computation.
