| Abstract: | With the continuously increasing in chip complexity and transistor density,the cost of chip testing is also increasing and even exceeds the cost of design and manufacturing.How to decrease the testing cost has become hot research area.Channel receiver chip of satellite digital television,as one of key components in set-top box,has growing requirement for the low cost testing.In this paper,a low cost testing scheme based on off-chip signal source is proposed by analysing the internal module,working principle and characteristics of the chip,which is implemented on ATE T6575.The results of production demonstrate that the proposed testing scheme can obviously reduce the testing cost of the chip. |
