The existing runs show the SR-switch memory astable is producing waveform data, but the timing measurements fail due to a .MEAS TRIG/TARG parsing error and earlier integrator-sign issues, so new parallel netlists focus on (1) a CROSS-only measurement approach and (2) robust offline-extractable .PRINT tables at practical resolutions.
