Abstract: Disclosed aspects relate to a clock distribution network of a synchronous logic device. The synchronous logic device has sub-circuits having different clock domains. The clock domains form a hierarchical structure. The clock distribution network has a clock source to provide a global clock signal. A programmable delay line associated with a sub-circuit generates a local clock signal for the sub-circuit by delaying the signal. A global skew control circuit can manage clock skew between the local clock signals. The global skew control circuit may adjust a delay, determine initial operations for the delay lines, verify whether it is possible to perform the initial operations, and perform a correction operation. The correction operation can include correcting the control commands such that the corrected commands lead to the same change of skew adjustment between the local clocks.

Abstract: An apparatus of performing a clock skew adjustment between N clock signals. 2(N?1) skew sensors are configured as successive pairs k, each pair k having a first skew sensor and a second skew sensor. The first skew sensor receives a third clock signal obtained by delaying the first clock signal by a first delay and a fourth clock signal obtained by delaying the second clock signal by a second delay, and generates first information based on the third and fourth clock signals. The second skew sensor receives a fifth clock signal obtained by delaying the first clock signal by a third delay and a sixth clock signal obtained by delaying the second clock signal by a fourth delay, and generates second information based on the fifth and sixth clock signals. A skew controller performs the clock skew adjustment based on the first and second information.

Abstract: A writing implement comprising a housing (2), a writing cartridge (4) arranged in the housing in a movable manner, and a control unit that displaces the writing cartridge between a first position in which the cartridge tip (6) protrudes from the housing for writing, and a second position in which the cartridge is retracted into the housing. In the first position the writing implement has a total length suitable for writing, and in the second position the writing implement is contracted. The writing implement exhibits improved handling without major structural modification, so that the writing implement can be brought into the writing position and also extended in a single hand movement. To achieve this the implement is provided with a depressor (8) which is configured as an extension of the housing and can be actuated to move the writing cartridge between the first and second positions, and which in the first position extends out from the rear end of the housing.
