Method for synchronously distributing a digital signal over n identical adjacent blocks of an integrated circuit

Abstract

The invention proposes a method for distributing a signal to each block Bof 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-DELon the path for conveying a signal Sfrom the input INcof the block to an internal electrical node Ndof the block for this signal S; providing for the timing delay circuit to supply N delayed signals corresponding to N different timing delays Δf, . . . Δf, . . . Δfseparated 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.
