WebApr 14, 2024 · Let say I have three signal : input clk_in , input rst_b, output clk_out. 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. 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. WebOct 26, 2024 · Clock gating is a way reducing dynamic Power dissipation by temporary turning-off clock of the Flops on certain parts of the logic or by turning-off enable on gated Flops. In other words, Flops are turned-on only if there is valid information to be stored or transferred. The accuracy with which these clocks are Turned-off is captured by clock ... scoundrel\u0027s wq

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;

For an SoC design to work reliably on an FPGA-based prototype, all the gated clocks in the design should be converted. If the gated clock is derived based on multiple clocks, or the gating logic is complex, then synthesis tools cannot do the gated-clock conversion.
