Abstract The paper discloses the idea of a new structure for a Test Pattern Generator (TPG) for detection of crosstalk faults that may happen to bus-type interconnections between built-in blocks within a System-on-Chip structure. The new idea is an improvement of the TPG design proposed by the author in one of the previous studies. The TPG circuit is meant to generate test sequences that guarantee detection of all crosstalk faults with the capacitive nature that may occur between individual lines within an interconnecting bus. The study comprises a synthesizable and parameterized model developed for the presented TPG in the VLSI Hardware Description Language (VHDL) with further investigation of properties and features of the offered module. The significant advantages of the proposed TPG structure include less area occupied on a chip and higher operation frequency as compared to other solutions. In addition, the design demonstrates good scalability in terms of both the hardware overhead and the length of the generated test sequence

Bus Architecture

Advanced microcontroller bus architecture (AMBA) protocol family provides metric-driven verification of protocol compliance, enabling comprehensive testing of interface intellectual property (IP) blocks and system-on-chip (SoC) designs. The AMBA advanced extensible interface 4 (AXI4) update to AMBA AXI3 includes the following: support for burst lengths up to 256 beats, updated write response requirements, removal of locked transactions and AXI4 also includes information on the interoperability of components. AMBA AXI4 protocol system supports 16 masters and 16 slaves interfacing. This paper presents a work aimed to design the AMBA AXI4 protocol modeled in Verilog hardware description language (HDL) and simulation results for read and write operation of data and address are shown in Verilog compiler simulator (VCS) tool. The operating frequency is set to 100MHz. Two test cases are run to perform multiple read and multiple write operations. To perform single read operation module takes 160ns and for single write operation it takes 565ns.

Precise Time

<span>In this paper, a Real Time Clock (RTC) system for a dedicated microcontroller is proposed to provide the customized microcontroller its own time and date system. The RTC is developed using Verilog Hardware Description Language (HDL) and simulated using Synopsys software. This RTC is developed with standard Advance Peripheral Bus (APB) to be interfacing with the microcontroller through Advanced Microcontroller Bus Architecture (AMBA). This RTC will be used as an on-chip RTC in the microcontroller system to provide precise time and date which can be used for various applications. The basic architecture of RTC, APB standard for interfacing the RTC with AMBA bus, and the result in term of RTL, waveform, and layout will be discussed in this documentation. For this research, the part covered is on the logic part of the RTC that is bus interface, register, frequency divider and counter.</span>

In this paper, we proposed BIST-based architecture to at-speed test of crosstalk faults for system-on-chip interconnects. This architecture includes IEEE 1500 wrapper enhanced cells intended for multiple victim test model test patterns generation and analysis test responses. One new instruction is used to control cells and test pattern generator controller in serial test access mechanism of the standard in order to fully comply with conventional IEEE 1500 standard.

Redundant Binary (RB) to Two’s Complement (TC) converter offers nonredundant representation. However, the sign bit of TC representation has to be handled using nonstandard hardware blocks. The concept of Inverted encoding of negative weighted bits (IEN) eliminates the need of sign extension and offers design only using predefined hardware blocks. NonRedundant Binary (NRB) representation refers to both conventional and IEN representations. The NRB representation is also useful considering problem related to shifting in Carry Save (CS) representation of a RB number. In this paper, we have proposed two new conversion circuits for RB to NRB representation. The proposed circuits of the RB to NRB converter are coded in Verilog Hardware Description language (HDL) and synthesized using the Encounter(R) RTL Compiler RC13.10 v13.10-s006_1 of Cadence tool considering ASIC platform. Considering 64 bits’ operand, the delay power product performances of proposed one-bit and two-bit computations offer improvement of almost 29.9% and 47%, respectively as compared to Carry-Look-Ahead (CLA). The proposed one-bit converter is also applied in the final stage of the Modified Redundant Binary Adder (MRBA). The 32-bit MRBA offers a delay improvement of 7.87% replacing conventional converter with proposed one-bit converter in same FPGA 4vfx12sf363-12 device.
