control scan
1.In the third part, we research the design idea based on Simple Network Management Protocol (SNMP) agent, and introduce the conception of SNMP agent module, First-In First-Out(FIFO) piping interface module, access point(AP)/access control(AC) scan module, MYSQL database interface module, receive trap module etc. .
6.Since high performance control logics are usually hard for non-scan test generation,DFT structures could be embedded as offsets in tradition,while it will cause manufacturing cost increase and performance overhead.In this paper,an indirect test generation method based on retiming is proposed,which could dramatically reduce the cost of non-scan ATPG without any loss of original optimized attributes.Experiments on some ISCAS′89 benchmarks show the benefits of our approach in enhancing ATPG of performance-driven logic.
9.The instrument has highresolution, specification of fast speed scan and remote-control ability over 50m distance.
