Serial NOR Flash Memory Model

Overview

Serial NOR Flash Memory Model provides an smart way to verify the Serial NOR Flash component of a SOC or a ASIC. The SmartDV's Serial NOR Flash memory model is fully compliant with standard Serial NOR Flash Specification and provides the following features. Better than Denali Memory Models.

Serial NOR Flash Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

Serial NOR Flash Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
