ABSTRACT:
An IC-chip testing system includes multiple digital state machines, and a master controller which controls the operation of those digital state machines by a particular method. In this method, the master controller first generates a command chain in which multiple commands for one particular digital state machine are concatenated together in a series. Thereafter, the master controller sends a single payload data packet embedded in a layered TCP/IP
etwork format, to that digital state machine. This single payload data packet includes the entire command chain. By concatenating many commands together in the command chain, the adverse effect of TCP/IP
etwork headers on the efficiency of transmission is overcome. In one particular transmission, efficiency is increased from 7.1% for sending a single command, to 89.4% for sending the entire command chain.
