1-Wire Master SOPC Module

I am currently integration the Dallas / Maxim 1-wire into our fpga's.

From Maxim i have received the ds1wm sources and the documentation. But the source is a fully asynchron design http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/ohmy.gif and does not match the documentation.

Before i reinvent the "wheel", does anybody know where a functional 1-Wire master ip core is available ? maybe one that is already been ported to niosII as an sopc http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/tongue.gif

Any comments welcome.
