How it works
If sel is high, then a counter is output on the output pins and the bidirectional pins (data_o = counter_o = counter).
If sel is low, the bidirectional pins are mirrored to the output pins (data_o = data_i).
How to test
Set sel high and observe that the counter is output on the output pins (data_o) and the bidirectional pins (counter_o).
Set sel low and observe that the bidirectional pins are mirrored to the output pins (data_o = data_i).
IO
| # | Input | Output | Bidirectional |
|---|---|---|---|
| 0 | sel | data_o[0] | data_i[0] / counter_o[0] |
| 1 | data_o[1] | data_i[1] / counter_o[1] | |
| 2 | data_o[2] | data_i[2] / counter_o[2] | |
| 3 | data_o[3] | data_i[3] / counter_o[3] | |
| 4 | data_o[4] | data_i[4] / counter_o[4] | |
| 5 | data_o[5] | data_i[5] / counter_o[5] | |
| 6 | data_o[6] | data_i[6] / counter_o[6] | |
| 7 | data_o[7] | data_i[7] / counter_o[7] |
User feedback
- mattvenn: just checked the counter and it works
- wongmatthew73: I used the same circuit I used when I simulated the design with an FPGA dev board (BASYS3). I used an oscilloscope to see the square waves of syncRectifierLs and syncRectifierHs outputs. Then I made sure that the duty cycle of both square waves would adjust proportionally as I increased the ADC voltage from 0V to 3.3V. My design worked flawlessly. Actually, I'm shocked that it worked, let alone worked exactly how I was hoping it would given that my typical experience with PCB designs is that they usually don't work properly or at all the first time.
