Title
Testing the configurable interconnect/logic interface of SRAM-based FPGA's
Abstract
The objective of this paper is to define a minimum number of configurations for testing the configurable modules that interface the global interconnect and the logic cells of SRAM-based FPGAs. In usual SRAM-based FPGAs, Configurable Interface Modules (CIMs) can be found between the global interconnect and inputs of the logic cells (input CIMs) or between output of the logic cells and the global interconnect (output CIMs). It is demonstrated that an input CIM that connects Nin segments to a logic cell input requires Nin test configurations and that an output CIM that connects a logic cell output to Nout segments requires 2 test configurations. Then, it is proven that a set of Kin input CIMs can be tested in parallel making the number of required test configurations equal to N in. In the same way, a set of Kout output CIMs is shown to require only 2 test configurations if Nout>Kout. Finally, it is shown that the complete mXm array of logic cells with Kin input CIMs and K out output CIMs can be tested with only Nin test configurations using the XOR tree and shift register structures
