SPI (Serial Peripheral Interface) Flash is the serial synchronous communication protocol developed by SPI Block Guide V04.01. SPI Flash VIP can be used to verify Master or Slave device following the SPI Flash basic protocol as defined in Motorola's M68HC11 user manual rev 5.0. It can work with Verilog HDL environment and works with all Verilog simulators that are support SystemVerilog.
SPI (Serial Peripheral Interface) Flash Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
SPI (Serial Peripheral Interface) Flash Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
