Hello Dear Readers, Today, I will explain how one can modeling an Internally and Gated clock using Verilog HDL. 1). Internally Generated Clocks: Internally generated clock signals use a system or master clock and generate output as an internally generated clock signal. But, internally generated clock signals need to be avoided as it causes the functional and timing issues in the design. The functional and timing problems are due to the combinational logic propagation delays. The internally generated clock signals can generate a glitch or spike in the output. This can trigger the sequential logic multiple times or can generate undesired output. Even due to violation of setup or hold time these types of designs have timing violations. It is always recommended to generate the internal clocks by using register output logic. But still due to the propagation delay of the flip-flop, the overall cumulative delay or skew can generate glitches or spikes in the design. As shown b...
