ic logic tester

[Diego Torres]

Hi everyone!

Do Some one  try to make a test over an ic? For example CMOS or TTL logic. I'm looking how to make test in circuit but I can't find any help... Example.... or may be a Library. I think LabVIEW most have something. Thanks in advance.

Your request is VERY open ended. LabVIEW is used by many semiconductor manufacturers for testing their chips, especially in the development departments, often in combination with Test Stand. But how to access those chip pins is very variable. Some projects I worked on were using rather complex PXI setups with all kinds of programmable power supplies, relay multiplexers and digital and analog IO. Others were using mainly programmable SMU (Source Measurement Units) for characterization of semiconductor parts. In some cases it is as "simple" as using a JTAG test probe to access the on board JTAG interface.

If you talk about a tester to identify chips, I would go with COTS solutions rather than trying to invent my own. It's simply a to complex topic to try to make your own.
