Abstract: A method of operating a computing device for detecting clock domain crossing (CDC) violation in a design of a memory device, the method includes parsing a Netlist to generate a circuit database, parsing a clock tree using the circuit database to generate a clock tree database, extracting a non-toggled point using the clock tree database to generate a false path database based on the non-toggled point, and extracting a CDC violation identified from one or more simulation waveforms using the clock tree database and the false path database.
