Principle analysis of FPGA / CPLD digital circuit

When the combinational logic generating the gated clock exceeds one level, it becomes very difficult to prove the reliability of the design project. Even if the prototype or simulation results do not show the static danger, there may still be danger. Usually, we should not use multilevel combinational logic to clock the trigger in PLD […]
