Detailed Description
The technical solutions of the present invention will be described clearly and completely with reference to the following embodiments, and it should be understood that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The technical essence of software definition is that original integrated hardware facilities are broken through, basic hardware is virtualized and standardized basic functions are provided, then the basic functions are controlled through control software, and more open, flexible and intelligent control services are provided. Currently, many researches are conducted at home and abroad for Software definition, such as Software Defined Networking (SDN), Software Defined Data center (Data center), Software Defined Storage (SDM), and the like. However, in the current software definition system, no matter SDN, SDDC and SDM, they can only implement software definition above the network layer, but there is no device capable of supporting software definition for the link layer and the physical layer, which means flexible, efficient and transparent interconnection and interworking of heterogeneous protocols cannot be implemented.
The software-defined interconnection technology is a completely innovative enabling technology, and the content of the technology comprises the aspects of interconnection protocol software-definable, interconnection bandwidth software-definable, interconnection port software-definable, interconnection topology software-definable and interconnection protocol conversion software-definable. The software-defined interconnection technology is responsible for finally solving flexible interconnection and intercommunication of any heterogeneous protocol, and specifically at least comprises a software-defined physical layer technology, a software-defined link layer technology, a software-defined heterogeneous protocol conversion technology and the like.
Currently, the software-defined interconnection technology can be verified by adopting a traditional UVM logic simulation mode, but the UVM simulation has defects in several aspects:
(1) due to the fact that heterogeneous protocols are converted in the software defined interconnection technology, conversion processing from an original protocol to a target protocol exists, whether the processed target protocol can meet the extra requirements of an upper protocol stack of standard endpoint equipment or not is judged, and current UVM simulation cannot temporarily cover the target protocol. Because the VIP (verification IP) of UVM simulation can only carry out traditional verification on the specification of a target protocol at present, the verification of protocol compatibility can only be ensured, and whether the target protocol obtained after the conversion of the software-defined interconnection technology meets the extra processing requirement of an upper protocol stack of standard endpoint equipment or not can not be ensured by the VIP, the test based on the real application scene of the standard physical equipment is the fundamental verification aiming at the brand-new software-defined interconnection technology.
(2) The simulation speed is slow, especially when the scale of the digital circuit is large, the logic simulation speed becomes slower, which causes the verification period of the whole project to become mediocre and the lead time of the whole project to be limited.
(3) It is impossible to verify the Clock Domain Crossing (CDC) processing logic, Clock recovery and Clock compensation logic of high-speed signals in the digital circuit, such as RapidIO protocol/FC (fiber bus) protocol/Ethernet protocol/PCIE (Peripheral Component Interface Express) protocol and other high-speed communication protocols.
