HBM2E Memory Model provides an smart way to verify the HBM2E component of a SOC or a ASIC. The SmartDV's HBM2E memory model is fully compliant with standard HBM2E Specification and provides the following features. Better than Denali Memory Models.
HBM2E Memory Model is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
HBM2E Memory Model comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
