Tool used: SYNOPSYS VCS Developed a verification environment to verify the basic functionalities of the ARM AMBA AHB Protocol. In case of AHB, there is only one Bus master at a time. The AXI protocol is based on a point to point interconnect to avoid bus sharing and therefore allow higher bandwidth and lower latency. Coverage analysis is a vital part of the verification process; it gives idea that to what degree the source code of the DUT has been tested. verification of AHB Protocol which provides the best framework to achieve CDV (Coverage Driven Verification) which combines automatic test generation, self-checking test benches, and coverage metrics to significantly reduce the time spent on verifying a design. my email id is -- [email protected] Further the design and the verification of AHB-Lite protocol. Let’s apply this to a bus protocol e. It is an available option for automatic SoC testbench generation. VC Verification IP for Arm AMBA Protocol. A step-by-step tutorial follows on how to connect the QVIP protocol checker for AHB-Lite bus connection. There are versions of QVIP that support various industry standard interfaces, see the overview in Fig. After bringing up the testbench, the Renesas engineers could enjoy the native extensibility of the e language and Specman Elite. connect to the multiple AHB slaves. Among three distinct buses of AMBA specification, AHB is a new generation of AMBA bus which is meant to address the requirements of high-performance synthesizable designs. Gaisler Research provides advanced AMBA bus monitoring functions that are used during the verification of the system. Verification of AMBA Using a Combination of Model Checking and Theorem Proving Hasan Amjad 1 Computer Laboratory University of Cambridge Abstract The Advanced Microcontroller Bus Architecture (AMBA) is an open System-on-Chip bus protocol for high-performance buses on low-power devices. The APB can interface with AMBA Advanced High Performance Bus Lite (AHB-Lite) and AMBA Advanced Extensible Interface (AXI). Therefore an efficient verification environment is needed. ASIC Verification Interview Questions SOC Verification Interview Questions AMBA AHB & AXI GENERAL Basic GVIM/VIM Commands Collection of SLIDES from Slide-Share Verilog Codes. protocols, we require verification IP's to get our design verified. Should be comfortable writing assertions for protocol validation. Our work is a case study of the synthesis of the widely and industrially used AMBA AHB protocol from formal specifications. AMBA protocol (AHB) is verified by achieving successful read & write operations for incrementing burst feature. An AHB protocol compliant Verification IP written using SystemVerilog, would then be.
