ONFi

ONFi

ONFi (Open Nand Flash Interface) provides an smart way to verify the ONFi host controller or ONFI Flash memory model of a SOC or a ASIC. The SmartDV's ONFi is fully compliant with standard ONFi Specification and provides the following features.

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