Hi Tim,
Many thanks for the MAX10 TSE reference design. It had gotten into quite a mess i think ! Its great that it was tested at 1G which is what i need to use. All my tests had been failing but as you say: not a good idea to change data and clock simultaneously! I will try your zipped project and see if i can get it to compiled and working properly. Which Quartus Version does this project belong to please ? I am hoping to use it in a Quartus 25.1 Std project eventually.
Thanks are also due then to Scott Prigmore for doing the fix up work !
Thanks very much, Dr Barry H
