Use Clock and Register-Control Architectural Features FPGAs provide device-wide clocks and register control signals that can improve performance. Use Global Clock Network Resources Altera FPGAs provide device-wide global clock routing resources and d
Optimizing Clocking Schemes Avoid using internally generated clocks (other than PLLs) wherever possible because they can cause functional and timing problems in the design. Use clock setting assignments on any derived or internal clocks to specify th
