A chip verification system includes a plurality of agent modules, a register model, and a scoreboard module. The register model includes a register database, a plurality of access modules, and a return module. Each access module corresponds to one of a plurality of attribute parameters. Each agent module transmits an address code of its sequence to the return module. The return module obtains, according to the received address code, an address subject and the attribute parameter corresponding to the received address code from the register database, and outputs the obtained attribute parameter. Each driver module calls, according to the received attribute parameter, the corresponding access module to perform an operation on registers of DUT circuit according to a read write command of the sequence. The scoreboard module records each performed operation to generate an operation record, and outputs a verification result according to the operation record and data in registers.

Chip verification system and verification method therefor

A method of testing a slave device of an Inter-Integrated Circuit (IC) bus is provided. The method includes the following steps: (A) starting a first read operation or a first write operation of the slave device, the first read operation or the first write operation including a sub-operation of sending a command, an acknowledgement signal, data, an address or a control byte to the slave device; (B) sending a start command or an end command to the slave device after or during the sub-operation; (C) after step (B), performing a second read operation or a second write operation on the slave device; and (D) after step (C), determining whether the second read operation or the second write operation is correctly performed.
