I have used VHDL a lot. VHDL is a digital design language for FPGA and can write RTL.

What is PYNQ ? Does is work as embedded operating system for ZYNQ PS or can also do FPGA design (ZYNQ PL) ?

Basically PYNQ runs on ZYNQ PS only, is that correct ? PYNQ can not be use to design and implement FPGA RTL based digital design. Or

Can we do/implement digital design on FPGA using PYNQ instead VHDL ?

Correct. PYNQ is not Python to RTL.
