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