LVDS VIP

Description and Features

Through the collaboration of businesses in the semiconductor, display, computer system, connector, and cable sectors, the Open LVDS Display Interface (Open LDI) protocol was created to serve as an open standard for the digital connection of display sources and display devices. The de facto industry standard for connecting display controllers to LCD panels in laptop computers has evolved into this standard. The Standard Open LVDS Display Interface (Open LDI) Specification is completely adhered to by the Open LDI. System Verilog, VMM, RVM, AVM, OVM, UVM, Verilog, System C, VERA, Specman E, and non-standard verification environments all natively support the Open LVDS Display Interface (Open LDI) Verification IP. The Open LVDS Display Interface (Open LDI) Verification IP also includes an optional, GUI-based Smart Visual Protocol Debugger.
