in fpga when gates in one cell are used completely, it switches to other cell and uses gates available in that cell. i want to know when it shows the gate count does it include all gates in that other cell or it includes only used cell in gate count??
There are no gates in an FPGA, so there is no gate count. And therefore a cell cannot be full of gates.
An ALUT (altera) or Slice(Xilinx) contains and LUT and a register (and some other little bits). But theres not gates. They are created by setting the LUT to a specific table.
