Hi,

for a redesign of a system with ADAU1442 and 5 AD1938 i want to replace the ADAU1442 with the ADAU1467. I try to remove the ADAU1442 in the hardware config, there is an error message "The selected IC is beeing used by one or more algorithmus..." which is clear.

Because there is a complex signalflow i don't want to draw the hole signalflow again. Is there "trick" to replace the ADAU1442 with the ADAU1467 without drawing the signalflow again ? I thought that all algorithmus form ADAU1442 should work on ADAU1467 too ?

I also tried "cut and paste" the signalflow, but there are an amount of errors.

Is there an overview of the differences between ADAU1442 and ADAU1467 ?

Hello mo-igb37,

There is a way you can trick the software but it only works for devices in the same processor family. The 1442 is a Sigma200 and the 1467 is a Sigma350. The code is very different. Since the code is encapsulated into the cells of the schematic you cannot just assign them to a different processor family.

So unfortunately you will have to draw the signal flow again. Look at the bright side. Usually when I draw it a second time I find cleaner ways to draw it or to improve the program.

I actually detailed how to do it in this post:

However, Like I said, in your case it will not work.
