I have a module "keeper" in Verilog language, but it can not be called by its top module when use ISE7.1i.For exsample:
module top(......);
input .....;
output .....;
keeper keeper(.a(),.b(),....);
endmodule
Load module top and module keeper into ISE7.1i Project Navigator, then you will find that module keeper is not included in the module top. When synthesis module top, Project Navigator will tell you "could not find module/primitive 'keeper' ". If I rename keeper to annother name such as "keeper1" but can not be "keep", all problems don't exist. Why? "Keeper" or "keep" is the key word or reserved word in ISE7.1i Project Navigate? Use synplify cann't exist this problem.
