WebJun 4, 2024 · So in this case, we have FPGA pins driving through buffers to data input wires or, if the output enable is set to one, data output wires are driving the pins as output. How would this look in VHDL, we have our output enable, data out as an input bus, data in as an output bus, and our IOpin, which sits at the IO boundary of the chip. WebMar 12, 2013 · The single tri-state buffer is created in VHDL using the following line of code: Y <= A when (EN = '0') else 'Z'; When the EN pin is low, then the logic level on the A input will appear on the Y output.

WebOct 9, 2024 · There are many ways to implement an AXI FIFO in VHDL. It could be a shift register, but we will use a ring buffer structure because it’s the most straightforward way to create a FIFO in block RAM. You can create it all in one giant process using variables and signals, or you can split the functionality into multiple processes. WebBut this sort of data shuffling would be tedious to implement, so instead let's use a circular buffer. That's a regular memory with an offset pointer that indicates where index 0 is located. When we get a new sample, we increment the offset and store the incoming data at the location it points to.

WebJul 6, 2015 · A couple of notes: (1) EN can be a single std_logic. (2) Then Y <= A when EN = '0' else (A'range => 'Z'); ought to work. (3) Using A'range attribute instead of others makes the size of the vector explicit which will help in places where the compiler can't tell the correct range for others. – user_1818839 Jul 6, 2015 at 11:03
