Abstract
The invention proposes a method for distributing a signal to each block Bj of a series of N adjacent blocks of identical design in an electronic circuit. It proposes, in an identical fashion for each of the N blocks, placing a timing delay circuit MUX-DELj on the path for conveying a signal Sc from the input INcj of the block to an internal electrical node Ndj of the block for this signal Sc; providing for the timing delay circuit to supply N delayed signals corresponding to N different timing delays Δf1, . . . Δfj, . . . ΔfN separated by an increment of elementary duration Δt that corresponds to the elementary delay Δt for transit of a block introduced into a conductive line; and selecting the delayed signal corresponding to the applicable timing delay according to the block in question, by means of an index signal propagated through the N blocks, and which is incremented or decremented on passage through each block.
