SDRAM Memory Model
SDRAM Memory Model provides an smart way to verify the SDRAM component of a SOC or a ASIC.
Overview
SDRAM Memory Model provides an smart way to verify the SDRAM component of a SOC or a ASIC. The SmartDV's SDRAM memory model is fully compliant with standard SDRAM Specification and provides the following features. Better than Denali Memory Models.
SDRAM Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
SDRAM Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
