Abstract

Configurable time-borrowing flip-flops may be based on configurable pulse generation circuitry and pulse latches. The circuitry may use a self-timed architecture that controls the width of clock pulses that are generated so that the pulse latches that are controlled by the clock pulses exhibit a reduced risk of race through conditions. Latch circuitry may be provided that is based on a pulse latch and an additional latch connected in series with the pulse latch. In situations in which there is a potential for race through conditions on an integrated circuit, the additional latch may be switched into use to convert the latch circuitry into an edge-triggered flip flop. Clock trees may be provide with configurable shorting structures that help to reduce clock skew. Low-contention clock drivers may drive signals onto the clock tree paths.
