<!-- 6. Critical Path -->
|
|
<h3>6. Critical Path Analysis</h3>
|
|
<p>The tightest path (WNS = +0.132 ns) is in the <code>ft601_clk_in</code> (100 MHz) domain: <code>ft601_rxf</code> input pad → 8 logic levels (IBUF + LUT1 + LUT3 + 4×LUT6 + LUT5) → <code>usb_inst/FSM_sequential_current_state_reg[2]/D</code>. This is the USB read FSM path and is unrelated to MTI or CFAR.</p>
|
|
<p>The <code>clk_100m</code> domain (where MTI, CFAR, and Doppler operate) has +0.634 ns slack — improved from Build 24's +0.287 ns. The MTI canceller adds no new critical paths.</p>

<h3>6. Critical Path Analysis</h3>
|
|
<p>The tightest path (WNS = +0.179 ns) is in the <code>clk_mmcm_out0</code> (400 MHz) domain: NCO sine LUT index register → LUT6 → <code>sin_abs_reg</code>. This is the same path that was critical in Build 21 and is unrelated to CFAR.</p>
|
|
<p>The <code>clk_100m</code> domain (where CFAR operates) has +0.287 ns slack. The Build 23 critical path (<code>cfar_inst/leading_sum → cross-multiply → alpha*noise DSP</code>, WNS = -0.309 ns) has been completely eliminated by the pipeline fix.</p>
