Problems solved by technology

However, although the chances of the verifier and the designer making the same mistake are small, this chance always exists. If the mistake is in the same place, since the design code and the verification code are exactly the same, once the same mistake occurs at the same time, it may never be possible. find out
In this way, the existing errors will affect the function and operation of the network switching chip, and there is no guarantee that the design of the network switching chip will meet the original intention of the design, which will affect the entire network, and such errors can never be found and corrected

Embodiment Construction

[0021] A kind of verification method of the ping-pong pairing mode of switching chip, it is characterized in that: be responsible for sending the sending port of sending data packet, be responsible for receiving the receiving port of receiving data packet and a data packet mailbox by mutually opposite sending and receiving data packet Composition, the verification path is as follows:

[0022] A. The sending port is responsible for sending the data packets sent to the chip port to the data packet mailbox. In the first-in-first-out (FIFO) manner, multiple Ethernet data packets enter the first-in-first-out mailbox or data packet channel in a certain order, and Mailboxes or packet channels come out in the same order first-in-first-out;

[0023] B. The receiving port takes out the data packet from the mailbox;

[0024] C. At the same time, the data packet obtained by the receiving port waits for the data packet to come out at the output port of the chip, and compares the two data ...

Abstract

This invention discloses a ping-pong pairing type verification method for switch chip consists of a transmitting port for mutual transmitting / receiving data package, a receiving port for receiving data package and a data package post box. Said invention can find and correct the errors occurred at same location and could not be found formerly to keep the function and operation of network switch chip.

Description

Technical field: [0001] The invention relates to a method for verifying the ping-pong pairing mode of an exchange chip. Background technique: [0002] Usually, the design of the network switching chip adopts the parallel method of design and verification to ensure that the design and verification codes conform to the original design intention. as attached figure 1 . The verifier and the designer complete the design according to their own understanding of the design requirements. It is generally believed that the chance of the verifier and the designer making the same mistake in the same place is very small, so they can check each other's mistakes, so that the design code and the verification code It ended up being exactly the same. However, although the chances of the verifier and the designer making the same mistake are small, this chance always exists. If the mistake is in the same place, since the design code and the verification code are exactly the same, once the sam...
