JESD204 (Serial Interface for Data Convertors) is the serial communication protocol developed used with ADC and DAC. JESD204A/B/C/D VIP can be used to verify transmitter or Receiver device following the JESD204 basic protocol as defined in JESD204. It can work with Verilog HDL environment and works with all Verilog simulators that are support SystemVerilog.
JESD204 Verification IP
is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
JESD204 Verification IP
comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
