FPGA clock gating implementation. Hello, I´m doing ASIC prototyping on a Virtex7 FPGA. There 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:. v (note that Verilog files have a * This process models a clock generator You can assume the state register is implemented with D flip-flops The clock period or cycle time, T c, is the time between rising edges of a repetitive clock signal In a single testbench , if more than one clock is needed with different duty cycle, passing duty cycle.
