Altera Primitives

Yeah the primitives you mentioned are understandable to GHDL as well.

Is there any primitive for the dedicated adders inside ALM like the way we have carry chain primitive(CARRY4) in Xilinx.If not then how do i use the dedicated adder.

Also when we use lut_input/output primitives how many luts are used up,as in how to know the lut count.for example, say we want to make a xor gate and we use two lut_input primitive and one lut_output primitive.

Then what will be the lut count.

I have attached a code with it.

I got the libraries under "install dir/eda/sim_lib" but i need libraries without timing simulation.....these primitives use timing simulation.

Any solution will be of great help.
