  scan design
  Scan-In, Scan-Out
  
     <electronics> (Or "Scan-In, Scan-Out") A electronic circuit
     design technique which aims to increase the controllability
     and observability of a digital logic circuit by
     incorporating special "scan registers" into the circuit so
     that they form a scan path.
  
     Some of the more common types of scan design include the
     multiplexed register designs and level-sensitive scan design
      (LSSD) used extensively by IBM.  Boundary scan can
     be used alone or in combination with either of the above
     techniques.
