High resolution programmable pulse generator

Abstract From the Canadian patent

A programmable pulse generator that uses high resolution programmable delay circuits (HRPDCs) as building blocks each, of which is capable of changing timing "on-the-fly" i.e. modifying the programmable delay within one tester cycle and without the limitations of existing delay circuits. The pulse generator comprises a timing control array that is subdivided into three components providing coarse delay fine delay and, extra-fine delay; a plurality of timing generators respectively controlled by the timing control array each, generator further comprising a plurality of HRPDCs programmable delay circuits, and fixed delay blocks appropriately combined to modify pulse delay and pulse edges …
