PROJECT TITLE :

Efficient Implementation of Scan Register Insertion on Integer Arithmetic Cores for FPGAs - 2016

ABSTRACT:

Scan flip -- flop insertion for aiding design for testability invitations additional hardware overhead, thereby deteriorating the performance of the circuit. During this paper, we have a tendency to shall demonstrate a novel FPGA based implementation of inserting scan registers in commonly used Finite State Machines and pipelined knowledge path circuits with no hardware overhead or compromise in performance. All our proposed styles have been realized employing a relatively low -- level design methodology involving target FPGA family primarily based primitive instantiation, including their constrained placement on the Xilinx FPGA cloth. Implementation results clearly reveal the superiority of our proposed architectures compared to equivalent circuits derived through behavioral modeling with respect to space and speed. Additionally, our proposed scan register inserted circuits compare favourably with circuits designed without the scan flip -- flops. Let alone this, lies the benefit of an automatic generation of the corresponding Hardware Description Language (HDL) and placement constraints and their portability among different advanced FPGA families from Xilinx.
