AMBA ACE4 Assertion IP

Overview

AMBA ACE4 Assertion IP provides an smart way to verify the ARM AMBA ACE4 component of a SOC or a ASIC. The SmartDV's AMBA ACE4 Assertion IP is fully compliant with standard AMBA ACE4 Specification and provides the following features.

AMBA ACE4 Assertion IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

AMBA ACE4 Assertion IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
