The initial phase shift information is loaded into the PLL whenever the PLL is reset (PLL_POWERDOWN_N = 0) or pulsing the LOAD_PHASE_N signal from high to low. User logic is required to vary the VCO phase settings from the initial value. You can repeat dynamic phase-shifting indefinitely. For example, in a design where the VCO frequency is set to 1,000 MHz and the output clock frequency is set to 100 MHz, performing 40 dynamic phase shifts (each one yields 125 ps phase shift) results in shifting the output clock by 180º, which is a phase shift of 5 ns. Fixed Fine Phase Shift mode sets the phase shift at the time of design. The phase shift value cannot be changed by the application as it is loaded during the FPGA configuration process. 2. Dynamic Fine Phase Shift mode has some phase shift value initially, similar to Fixed Fine Phase Shift, which is set during FPGA design configuration time.In our case "altpll50", an instantiated PLL component we will create later on in this tutorial. clock port: Now, I lied a bit that we didn’t have to write any VHDL or SystemVerilog. As you can see, we connect the clock port to the expression CLOCK_50(0), which is a. Four-phase logic. Four-phase logic is a type of, and design methodology for dynamic logic. It enabled non-specialist engineers to design quite complex ICs, using either PMOS or NMOS processes. It uses a kind of 4-phase clock signal .

Revised description of STARTUP_WAIT, page 81 . Updated RST description in Table 3-5, page 74. Requested Phase: Enter the phase shift needed with respect to the reference clock. If the configurator is not able to generate an exact match of the requested phase, it gives two possible phases to select from—one above (actual higher) the requested phase and one below (actual lower) the requested phase. 就是Phase shift的首字母, 看下面这幅图,是时钟产生向导图: 可见,我选了动态相位偏移之后,就会出现这些以PS开头的端口。 而由这篇博文也知道:通过Clocking Wizard定制和生成一个IP核(MMCM)(Virtex7)(ISE版),动态相移的作用是改变输出时钟之间的相位关系。Approximately one-fourth of eukaryotic mRNAs harbor at least one m6A-modified base, but how is this regulated? This study shows that cells can use liquid-liquid phase separation to regulate dynamic assembly of the mRNA m6A methyltransferase complex (METTL3/METTL14/WTAP), with stoichiometries that depend on condensate partitioning in a substrate binding-dependent manner.Output clocks must be enabled sequentially. You can rename the output clocks in the output clock table itself. You can specify values for the output clock frequency, phase shift, and duty cycle assuming that the primary input clock is the active input clock.

Example: Mar 01, 2010 · The initial phase shift is static phase shift information set through the CCC configurator. The initial phase shift information is loaded into the PLL whenever the PLL is reset (PLL_POWERDOWN_N = 0) or pulsing the LOAD_PHASE_N signal from high to low. User logic is required to vary the VCO phase settings from the initial value. @rangaraj, . What you are asking about is something called "Dynamic Reconfiguration". You'll find the details regarding "MMCM and PLL Dynamic Reconfiguration" in this App note. As I recall, though, the MMCM needs to generate an internal clock between 800MHz and 1600MHz, which you then divide down by an integer amount--something between 1 and 32, although I can't find these numbers right now.The VFC (voltage-to-frequency-converter) circuit in Figure 1 achieves a wider dynamic range and a higher full-scale output frequency - 100 MHz with 10% overrange to 110 MHz - by a factor of 10 over any commercially available converter. ...
