HyperRAM Memory Model

HyperRAM Memory Model provides an smart way to verify the HyperRAM component of a SOC or a ASIC. The SmartDV's HyperRAM memory model is fully compliant with standard HyperRAM Specification and provides the following features. Better than Denali Memory Models.

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

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