clock gating verilog写法 Clock gating是一种广泛用于减少功耗和提高芯片性能的技术。简单来说,它是通过控制时钟信号的流动来实现减少功耗和提高性能的目的。在这篇文章中,我们将探讨如何使用Verilog语言来实现Clock gating的设计。 第一步:定义时钟及其控制信号 首先,我们需要定义时钟信号和时钟控制信号。这可以通过在...
I am using clock gating in cadence RTL compiler, but there is no ICG cell in the library. So I implemented an ICG cell with verilog code, which is active high ICG cell. module ICG_posedge( input ck_in, input enable, input test, output ck_out ); reg en1; wire tm_out, ck_inb;...
synthesized them with gated clock. Then I simulated the synthesized Verilog netlist using the same test bench for the original Verilog code. The simulation didn't consider any timing information since we were testing the logic integrity. The logic of the synthesized netlist was verified successfully...
1) Latch-based clock gating 2) Latch-free clock gating. Latch free clock gating The latch-free clock gating style uses a simple AND or OR gate (depending on the edge on which flip-flops are triggered). Here if enable signal goes inactive in between the clock pulse or if it multiple ti...

flops which share a common enable term have RTL clock gating implemented, the flip-flops will consume zero dynamic power as long as this enable term is false. The Verilog code in Example 1 is an RTL description of a three-bit up counter. ...
