Abstract
This paper describes the test and measurement of high-frequency analog/RF cores in a mixed-signal system-on-chip (SoC) environment using an embedded tester core. A new test methodology has been developed in which high-frequency tests are performed on-chip, but the control and test results are transmitted over the lower bandwidth connectivity associated with the SoC I/O terminals. A low-frequency analog signal is used to modulate a high-frequency squarewave and the resulting waveform is applied to a high-frequency circuit-under-test (CUT) as a test stimulus. The CUT's response is sampled using a coherent subsampling technique and the captured samples are transmitted at low-speeds off-chip from the SoC. A coupled phase-locked-loop and delay- locked-loop structure is employed to generate test waveforms in the 2.7-GHz range and to support high-resolution sampling with a sampling resolution of less than 10 ps. Simulation results using a reference low noise amplifier as a CUT shows the effectiveness of the proposed test method. The tester core has been sent for fabrication in CMOS 0.18-mum technology with a target area of 1 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> .

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
