This study describes a hardware modeling environment of built-in-self-test (BIST) for System on
Chip (SOC) testing to ease the description, verification, simulation and hardware realization on Altera
FLEX10K FPGA device. The very high speed hardware description language (VHDL) model defines a main
block, which describe the BIST for SOC through a behavioral and structural description. The three modules
test vector generator, circuit under test and response analyzer is connected using its structural description. 8-bit
pseudorandom test vector generator is a linear feedback shift register circuit consists of D latches and XOR
gates produces 255 different patterns of test vectors for CUT which consists of a 3 to 8 line decoder and a 4 bit
adder circuit. In response analyzer, the multiple-input pattern compressor circuit is used to produce signature
and a comparator circuit is used for signature analysis. The design is modularized and each module is modeled
individually using hardware description language VHDL. This is followed by the timing analysis and circuit
synthesis for the validation, functionality and performance of the designated circuit, which supports the
practicality, advantages and effectiveness of the proposed hardware realization for the applications with a
maximum clock frequency of 31.4 MHz.
Key words: Built-in-self-test, circuit under test, design for testability, latches, system on chip, VHDL,
