68060 testing on Replay board

[mikej]

So, I've picked up 15 x 68060 E41J mask set devices from two suppliers in China for testing of the daughter boards.

I'll use the Replay board+daughter board and a ZIF socket to do screening at the supplier later.

Running up workbench is not a bad test, but does anybody have ideas on how to do a more thorough test? Is there any CPU test suites I can use to test all aspects of the device?

I also need to read the id register to verify the mask revision.
Any help appreciated!
Cheers,

Good advice.
I'll look into the test suite.
Ideally I would have something fairly automated that says go/no-go and does not take too long. May have a lot of devices to go through.

Any pics of your 060 ?


This one for example is a fake :

I'll take some. Can you tell from the date code etc?

seems someone on natami forum have written some testcases, i might ask around if you dont want to do that yourself.

Would be great if you could.

Written on the 060 : 0124 = year 2001, week 24

Why is that a problem? Were they not manufacturing them at that point?

I recently purchased an MC68040 L88M from chinese supplier utsource, which I believe to be fake...

It is a risk. I have visited two suppliers and have an agreement to swap chips I don't like - so it is in their interest to give me good parts. However, I do need to come up with a decent test suite. Reading the PCN is easy and will validate the mask, however I still need to make sure the chip is fully functional.

Edit, they are not fake but may be reprinted - for example mask set changed, or just broken.
