eSPI (Enhanced Serial Peripheral Interface) is the serial synchronous communication protocol. It includes an extensive test suite covering most of the possible scenarios. It performs all possible protocol tests in a directed or a highly randomized fashion which adds the possibility to create the widest range of scenarios to verify the DUT effectively. It can work with Verilog HDL environment and works with all Verilog simulators that are support SystemVerilog.
eSPI (Enhanced Serial Peripheral Interface) Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
eSPI (Enhanced Serial Peripheral Interface) Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
