Hi,

I want to try and synthesize multibit multiplexers from my code so that a 4-bit 2:1 multiplexer gets mapped to a single cell from the technology Liberty library. It does not seem to work no matter what I do. I want to make sure I describe the cell correctly in the library file and that I use the HDL constructs and DC compiler commands.

Any help or experience with inferring and synthesizing multi-bit cells?
