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...
