hw multiplier for Cyclone

With NIOS-1 i could select three implementations for multiplications (sw, mul_step, mul). In Nios-2 this feature is complety missing. Is there any way to tell the SOPC-Builder for NIOS-2 to integrate...

I don&#39;t think you can, I think you are stuck using the standard inst_name(A,http://forum.niosforum.com/work2/style_emoticons/<#EMO_DIR#>/cool.gif ; format.

Try editing the ptf file of the nios to see if you can get it working there (James a while back showed me how to disable the hardware multiplier in that file so maybe you&#39;ll be able to invoke it???? assumming that hardware implementation for that in cyclone is already present). <----- Really doubt it will work though.
