How to add Microzed board in Xilinx ISE 11?

Even if you could add the board to the tool chain, the compiler(s) in the ISE 11 cannot generate a bitstream for a z7020.

You'll need to transition to Vivado to use the z7020.

Thank you Metaforest for your reply.
Okay, I already have Vivado and SDK installed and have already made some progress in booting Peta Linux from the QSPI, and tried writing some C code to turn on D3.
But what I am really interested in is learning VHDL proramming. I just need to get started by creating a simple combinational circuit in VHDL, and transfer it to the FPGA.

Would you please provide me with some guidance?

Thanks.

If you want to learn VHDL then a MicroZed board is the wrong hardware.

If it's all you can get/afford then you'll need to work with Vivado but the task of doing simple FPGA stuff is much harder on the Zynq based systems.

You can get low cost boards supporting older Altera and Xilinx FPGAs quite cheaply from Aliexpress.

The cheapest boards I know of come from SiPeed like this one:

The Gowin tools are not as good as Altera or Xilinx but the entry cost is certainly low.

I placed the order for the Tang Nano 9K.
