Re: synthesis tools

My question is,
is it worth using these expensive tools when there are also synthesis
tools created by the manufacturers of the FPGAs such as xilinx ISE
which is free.

Yes. They have better quality of results and less bugs. Well, Synplify
does anyway.

(I use xilinx exclusively. Sorry to the Altera fans out
there).

No doubt they will be gutted.

Secondly are the first tools much much more efficient than the
ones xilinx offers such that the gain obtained from them offsets the
cost of the tool.

Depends on the design.

Thirdly which one is better for Xilinx FPGAs

Synplify Pro.

Cheers,
Jon
