Using pulsed latches instead of flip-flops is a solution that has been thoroughly studied for its advantages in speed, density, and power consumption reduction  . Even so, this solution has not been widely adopted by standard cell library providers because of the difficulties related to timing verifications: pulse width integrity and hold time closure. There is also a lack of EDA tools natively supporting this feature. Dolphin Integration delivers standard cell libraries based on pulsed latches (SESAME uHD libraries) that can be used in standard design flows and fully compatible with the most common EDA tools.
