Honored Contributorabout the tri internel
hi: I want to connect my FPGA(cyclone ep1c6240c8) with my 51mcu .and there are adc and dac in my fpga board . I want to build a system in fpga to control my data fle.such as I can use ad and store...

Honored Contributor --- Quote Start --- I know that cyclone can't build tri internal --- Quote End --- That's right, because no respective hardware exists in a FPGA. FPGA internal connections are basically oneway. But you can, of course use internal tristate functions in a behavioral logic description. They are converted to multiplexers by the design compiler, achieving the same logical behaviour as a tristate hardware. So I don't exactly understand, what's your problem in connecting data from different sources in a FPGA. I don't see a particular restriction for your project.
