Open LVDS Display Interface(OpenLDI) specification was developed through the cooperation of companies in the semiconductor, display, computer system, connector, and cable industries to be an open standard for the digital connection of display sources and display devices. This standard is an evolution of the de facto industry standard for the connection of display controllers to LCD panels in notebook computers. The SmartDV VIP for OpenLDI is fully compliant with Standard Open LVDS Display Interface(OpenLDI) Specification.
Open LVDS Display Interface (OpenLDI) Verification IP is supported natively in SystemVerilog, VMM, RVM, AVM, OVM, UVM, Verilog, SystemC, VERA, Specman E and non-standard verification env
Open LVDS Display Interface (OpenLDI) Verification IP comes with optional Smart Visual Protocol Debugger (Smart ViPDebug), which is GUI based debugger to speed up debugging.
