WebThere is one main clock that supplies the design. This main clock (from a PLL) is split into two clocks - one that´s always running and one with a clock gate. This is to turn off some parts of the design to save power. So, it roughly looks like this: cpu_clk = main_pll_clk_out; gated_cpu_clk = main_pll_clk_out & enable; WebNov 6, 2015 · 1) Yes. You are creating a design, part of which is being driven by a gated clock. Perhaps the only bit that isn't is your clock divider logic. 2) All clocks will be reported. However, you're likely to see large, unwanted skews on your derived clocks. 3) Yes. Generally gated clocks are bad for a design.

How can I get an assertion to check if clk_out is toggling only after 2 clk_in cycles after the rising edge of rst_b. The assertion should fails if the clk_out is delayed more/less than 2 cycles and the assertion should also fail when clk_out stop toggle before rst_b goes 0. " - Crg clk gating

WebJun 26, 2003 · The multiplexer (MUX) has one control signal, named SELECT, which either propagates CLK0 to the output when set to “zero” or propagates CLK1 to the output when set to “one.”. A glitch may be caused due to immediate switching of the output from Current Clock source to the Next Clock source, when the SELECT value changes. WebHere, the scenario is that, the antecedent is true and the consequent is checked between 1 & 100 clock cycles. After the antecedent, the clock is stopped due to clock gating for some time and then the clock starts ticking again. The signal my_prio [rx_prio] is asserted after the clock gating but again within 100 clock cycles.
