In-system programming is a mainstream feature in programmable logic devices (PLDs), offering system designers and test engineers significant cost benefits by integrating PLD programming into board-level testing. These benefits include reduced inventory of pre-programmed devices, lower costs, fewer devices damaged by handling, and increased flexibility in engineering changes. Altera provides software and device support that integrates in-system programmability (ISP) into the existing est flows for the Agilent 3070 system. This chapter discusses how to use the Agilent 3070 test system to achieve faster programming times for Altera's MAX?II devices. ……
