XC3000 reverse engineering

Hi all,

 

  I need to fix a bug in a XC3000. Unfortunately I do not have the source code, but I do have the PROM content.

Is it possible to regenerate PROM contents into schematics code or similar but readable?

 

THank you

Hi

 

technical, yes is the answer, especially if you know the device,

 

it's what certain companies in 'other parts of the world' have done, revere engineering. 

 

But, practical,

 

NO is the answer,

 

it cost a LOT of money to do ..

Well in principle - no.

But if you need only a small change in a LUT - then you can use the FPGA Editor and make the appropriate changes there.

 

It is some work of course - but doable.

Hi

 

An aside I know, but I seem to remember fine tuning the 3000 series using the PIP editor, 

 

does that still exist ?
