HBM DFI Assertion IP

Overview

DFI HBM Assertion IP provides an efficient and smart way to verify the DFI HBM designs quickly without a testbench. The SmartDV's DFI HBM Assertion IP is fully complian with standard DFI HBM Specification.

HBM DFI Assertion IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env

HBM DFI Assertion IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
