thanks for the answer of bkucera.it seems that i have to write hal myself. but there are many differences between cs8900 and lan91c11,so it is hard to say whether i can work it out.

is there verilog or vhdl code of cs8900 so i can build a new component in sopcbuilder?

You don't need hdl to create a cs8900 component. Copy the LAN91C111 folder to a new directory and look at the files inside with a text editor, specifically the PTF file. Rename everything that says LAN91C111 to CS8900, save, and reopen SOPC builder. You should have a CS8900 component now.

From there you'll need to modify the PTF file to have the right inputs/outputs, and you'll need to modify the driver code to work with the CS8900.
