SYD8811_dtm_tx_adjust_power测试说明1

### SYD8811_dtm_tx_adjust_power测试说明知识点详解 #### 一、测试背景与目的在深入了解本测试之前，我们首先需要明确几个关键概念。SYD8811_dtm_tx_adjust_power测试主要关注的是DTM（Digital Test Mode）发射...

[DRC PDRC-182] PLL_adv_ClkFrequency_div_no_dclk: The computed value 666.667 MHz (CLKIN_PERIOD, net nfc_clk) for the VCO operating frequency of the PLL site PLL_X0Y11 (cell design_1_wrapper_i/design_1_i/nfc_8ch_v_wrapper_1/inst/ch0_dqs_inst/inst/top_inst/clk_rst_top_inst/clk_scheme_inst/GEN_PLL_IN_IP_USP.plle4_adv_pll0_inst) falls outside the operating range of the PLL VCO frequency for this device (750.000 - 1500.000 MHz). The computed value is (CLKFBOUT_MULT * 1000 / (CLKIN_PERIOD * DIVCLK_DIVIDE)). Please adjust either the input period CLKIN_PERIOD (12.000000), multiplication factor CLKFBOUT_MULT (8) or the division factor DIVCLK_DIVIDE (1), in order to achieve a VCO frequency within the rated operating range for this device.

这是一个Vivado综合时出现的警告，意思是PLL（锁相环）的...建议你调整输入时钟周期CLKIN_PERIOD（12.000000）、乘法因子CLKFBOUT_MULT（8）或除法因子DIVCLK_DIVIDE（1），以便在该器件的额定工作范围内实现VCO频率。

[DRC PDRC-34] MMCM_adv_ClkFrequency_div_no_dclk: The computed value 500.000 MHz (CLKIN1_PERIOD, net clk_in1_clk_wiz_main) for the VCO operating frequency of the MMCME2_ADV site MMCME2_ADV_X1Y5 (cell clk_wiz_main_inst/inst/mmcm_adv_inst) falls outside the operating range of the MMCM VCO frequency for this device (600.000 - 1440.000 MHz). The computed value is (CLKFBOUT_MULT_F * 1000 / (CLKINx_PERIOD * DIVCLK_DIVIDE)). Please run update_timing to update the MMCM settings. If that does not work, adjust either the input period CLKINx_PERIOD (10.000000), multiplication factor CLKFBOUT_MULT_F (5.000000) or the division factor DIVCLK_DIVIDE (1), in order to achieve a VCO frequency within the rated operating range for this device.如何解决

2. 调整输入周期：您可以尝试调整输入时钟的周期(CLKINx_PERIOD)，使得计算得到的VCO频率在操作范围内。根据错误信息，当前的输入周期为10.000 ns。您可以根据需要适当增加或减小该值，然后重新运行时序分析和生成...
