Toggle Flash Memory Model

Overview

Toggle Flash provides an smart way to verify the Toggle Flash host controller or Toggle Flash memory model of a SOC or a ASIC. The SmartDV's Toggle Flash is fully compliant with standard Toggle Flash Specification and provides the following features.

Toggle Flash Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

Toggle Flash Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
