opencores ip

Altera_Forum · ‎10-19-2004

i want to use the opencores ip and they offer only the verilog files for the components not the class.ptf. has somebody experience with building such a class.ptf or maybe a downloadsource for that file?? http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/rolleyes.gif

Dear piece-of-cheese,

There is a company that has ported the opencore ip to a NIOS processor. You can find that company at www.maco-engineering.de.

They can e-mail you the ptf file.

Regards,

Hans

piece-of-cheese,

I have been using several opencores projects. And for the most part,

I've been quite pleased. In general, there are two types of interfaces

you'll find: (1) wishbone, (2) generic ... neither of which will provide

any ptf (or avalon support for that matter). You'll have to add the

blocks to your system via an interface to user logic.

WRT wishbone: I tried a few times to replace the wishbone interface with

an avalon interface ... and eventually decided it was quicker (and more

maintainable) to just insert a wishbone-to-avalon bridge.

If it's generic (e.g. like the crypto cores for example), you can just

write your own avalon wrapper.
