Abstract: 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.

Abstract: The invention belongs to the technical field of waste cloth recovering and reusing, and particularly relates to waste-cloth-containing recovered fiber coating slurry and coating, and a preparation method thereof. 0.5-8 parts by weight of recovered fiber of waste cloth, 95-110 parts by weight of waterborne polyurethane, and 4-6 parts by weight of curing agent are prepared into recovered fiber coating slurry. The recovered fiber coating slurry is printed on a base cloth or a base plate, and dried to obtain a recovered fiber coating having a thickness of 0.1-1.0 mm. According to the technical solution provided by the invention, the field of physical method recycling of waste cloth is expanded to coating. Because the particle size of recovered fiber of the waste cloth is fine, the recovered fiber coating obtained by mixing waterborne polyurethane with a curing agent in a proper proportion has excellent abrasion resistance and mechanical properties.
