Some FPGA vendors offer IP core generators (e.g. Core Generators from Xilinx) which can be used to generate netlists of circuit modules of various types and complexities for FPGA designs. My question is how often do you use these tools provided by FPGA vendors.
A lot, as it makes routing easier and takes up less gates than synthesized blocks. Often makes the difference between i.e. a 30k or 40k gate device. So, saves money
I use the ip core generator tools as much as posssible.......cause.....it saves time (like ...in case u were gonna write ur own code for lets say a CORDIC Algorithm......it would be lot easier and less time consuming to use the coregen to implement it) and secondly makes ur routing a lot easier.
Its always preferable to use core gen's ..since it is highly optimised for that device family and also
reduces lot of time & effort.i use it frequently
