Design for test (DFT)


I am doing research in two DFT related fields:

    - RTL ATPG and
    - Single Cycle Access structures for testing

in order to finally combine these two reseach fields (see below).

RTL ATPG


In RTL ATPG we derive stuck-at patterns from RTL. With my proposed "
Gate Inherent Faults" solution, you are able to generate 100% stuck-at coverage on gate level with pattern solely generated on RTL for the first time. The following paper covers this:

T.Strauch, "A Novel RTL ATPG Model Based on Gate Inherent Faults (GIF-PO) of Complex Gates"
, 20. Workshop Methoden und Beschreibungssprachen zur Modellierung und Verifikation von Schaltungen und Systemen, MBMV 2017, 8-9 February, Bremen, Germany, pp.  117-128

Also submitted to Cornell University Library, 15th December 2016, https://arxiv.org/abs/1612.05166 or here.

Single Cycle Access Structures


Single Cycle Access Structures - or better known as "Random Access Structures" replace the classical scan based approach with a more memory like single cycle read and write access to individual register lines. In this paper I argue, that my proposed solution can be seen as a reasonable alternative to existing methods:

T.Strauch, "Single Cycle Access Structure for Logic Test", IEEE Transactions on VLSI, vol. 20, no. 5, May 2012, pp. 878-891, http://ieeexplore.ieee.org/document/5753986.

Surprisingly, this paper has been copied over multiple times.

Applying RTL ATPG on a Single Cycle Access Structure


The key goal is now to apply the aforementioned RTL ATPG method on a single cycle Access structure in order to better utilize multi-cycle capture cycles:
